TITLE: Re-smelting of Scrap CrNiMnN Austenitic Steels
Hutnickg
PERIODICAL:
listy, 1961, No.1, PP.13-19
TEXT: Sufficient experience is now available on the use of
18/8 type CrNi steel scrap. New problems arose in conjunction with
the development of new low nickel content economy steels. As a
result of efforts over many years, nickel-tree austenitic steels
Mnl7Cr7Ti (6SN 17481) and also Mnl?CrlOV (CSN N? 482), Mnl7Cr7MoV
(6SN N7 483) have been developed. From 1957 onwards, much attention
has been paid in Czec-hoslovakia to substituting austenitic stainless
CrNi 18/8 steels by steels with a higher Mn content plus a nitrogen
content', as for instance the steel Crl8MnlONi4N (6SN 17460) and also
type Crl6Mnl5N (6SN N? 470), which is to be introduced shortly.
In both cases the manganese content is between 10 and 18%, which
influences appreciably the technology of smelting charges Pontaining
such scrap. The basic consequences caused by the difference in
the chemical behaviour of the individual elements are reviewed.
First, a theoretical analysis is given of the phenomena taking
place during the refining by means of oxygen. Particular attention

Re-smelting of Scrap CrNiMnN Austenitic Steels
is paid to calculating the reaction heat. The theoretical results
arrived at confirmed the practical results obtained by Pachaly
(Ref.10) on processing 100% scrap of the steel Mnl9CrIONil.5. The
slag formation was controlled in such a way as to prevent develop-
ment of manganese silicates, i.e. prior to blow;ng oxygen the
melting slag was drawn off and new6 purely lime ilag was prepared.
Oxygen blowing was started at 1635 C and the refliing proceeded at
a speed of 0.02% C/min down to 0.06% C, Following that., the slag
was reduced by granular Al and drawn off. The bath temperature
increased to 1945 C. The Or utilisation was 96%, that of Mn was
66%. This experimental melt is dealt with in another paper
(Ref.11) but some of the relevant data are contained in Table 4.
Experiments on practical methods of processing scrap of these high
Mn content economy steels h,~Lve been going on since 1955. Some of
the data are discussed, SVUMT, jointly with the gmeral works, Brno,
started experiments in 1959 on solving the proble-m-UT-u-s-117-g internal
scrap of CrNiMnN and CrMnN stainless austenitic steels. Some of
the results obtained in three experimental heats are described.
There was particular interest in the behaviour of nitrogen. It was

found that,after an initial drop, the nitrogen content remains
unchanged. After evaluating the results of the first oxygen blast
re-smelting of the CrNiMn steel scrap., two further melts were
proceeded with in a 1-ton capacity are furnace. The charge
consisted of only 50% alloy scrap, the rest was carbon steel scrap.
More intensive oxygen blowing was applied, more attention was paid
to the reduction of the oxiding slag and the high temperatures at
the end of blowing in oxygen were utilised for rapid smelting of
further alloying additions, primarily ferrochromium, as a result
of which a quick drop in the temperature of the bath and the
lining to the normal. value was achieved. The results of this heat
are tabulated. The following conclusions are arrived at:
1. 50 to 60% alloy scrap can be used in the charge.
2. The smelting should be carried out in such a way that,prior to
blowing in oxygen, the melt should contain 0,,25 to O~30% C,
3. Prior to blowing oxygen., the -,lag shouid be prepared with lime
in such a way as to avoid formation of manganosilicates,
4. Blowing of oxygen should be started at the highest possible
temperatures and should be continued without interruption and with

the maximum permissible intensity.
5. The bath should be decarburized only to the .5pecific. upper 1-imit
of the carbon content.
6. After termination of the oxidation period, there should be a
reduction of the slag which contains metal oxides and then the bath
and the lining of the furnace should be cooled as quickly as
possible by throwing in lump scrap or alloying additions.
7. After reduction, the slag should be drawn off as quickly as
possible and the melt should be terminated in accordance with the
specified requirements.
Some Czech works have already tried re-smelting of such scrap in
open hearth furnaces but this was done exclusively in the manufacture
of steel intended for further shaping operations, In the described
experimental melts, monitoring of the temperature was not entirely
satisfactory due to the lack of suitable equipment for measuring
the bath temperature. Also it was not possible to weigh the metal
in the slag durin the process of smelting. Acknowledgments are
expressed to Vl. kteffek and Engineer P. Fremunt for practical

Influence of Molybdenum and Copper on the Properties
of Stainless Chromium
Hutnickof listy, 1961, No. 8, PP- 553 - 560
TEXT: According to data published in the literature
(Ref. 2 - Copper in Cast Steel and Iron. Copper Development
Association, London), high-alloy chromium steels containing
2-30'c S! and 1.5-20,' Cu have a high resistance to alum
and are extensively used in the food-processing industry.
An increased C content in chromium steels reduces their resistance~
to corrosion, particularly after unsuitable heat-treatment.
However, low-carbon chromium steels cause difficultiegin the
manufacture of castings of complex shapes. Therefore, higher
C contents are used and the unfavourable influence of the C
content is compensated by adding Cu. Although the effect of
Mo on chromium steels is Imown, the authors are not aware of
any published Information on the combined influence of Cu and Mo

on the properties of chromium steels. This is in spite of
the fact that such steels are being manufactured, for instance
the Czech steel Poldi-AKlBC (chemical composition: 0.120% C,
0.50% Nn, 0.251,',, Si, 16.151;" Cr, 0.20101 Mo and 1.75% Cu) and the
ferritic chromium steel for use in the chemical industry,
containing 0.6-0.8o,.' C,max. 0.7694 Mn, max. 2% Si, 28.0 - 30-00% Cr,
2.0 - 2-5 /0 Ni, 2.0 - 2-50% Mo and 2.0% Cu. The authors
considered it interesting to investigate the influence of Cu
and Mo on the properties of chromium steel and this paper
contains the results of these investigations. A total of 11
heats was produced with chemical compositions varying between
the following limits: C 0.6 - 0.11%; Cu 0 - 6.1100;
Cr 14-58 - 26.66j' and Mo 0 - 3-910%. O~he heats were produced
in n 20-kg high-frequency furnace, using as a:charge:1ow-carbon
steol, low-carbon ferrochroinium, low-carbon ferromolybdenum and
cop,,..or. Of the mechanical properties only the hardness was
-easured. In agreement with data published in the literature,
heats trith higher copper contents showed a higher hardness, both

tests showed that addition or Cu brought about pronounced

A detailed analysis allowed grouping the time dependence of
the weight loss due to corrosion into three basic groups:
linear dependence (in hydr8chloric acid and, in some cases,
also in nitric acid at 80 C); parabolic dependence with
steepness increasing with time (NaHSO 3 solution) and, finally,
corrosion rate decreasing with time and characterised by a
curve which flattens out. The corrosion tests have shown
that steel containing 25% Cr, 2% Mo and 2% Cu had the highest
resistance to corrosion, which almost equalled the Czech
steel 6SN 17241. This type of steel was not investigated in
the group of the 17%1 chromium steels. In the latter steel,

Mo improved the resistance to corrosion in solutions with free
so2 , whilst Cu improved the resistance to corrosion in
organic acids. On the basis of laboratory results, SONP Kladno
produced two 50-kg heats In a high-frequency furnace with
chemical compositions which proved the most favourable in the
laboratory tests. The compositions of these heats (in %) were
qS follows:
Heat C Mn Si P S Cr Mo CU
A 3829 0-13 0-53 0,37 0.019 0.021 15-52 2.05 2.01
B 3830 OolO 0-54 0-30 o.o26 0.017 24o75 1.75 1o95 o
The ingots from both heats were forged into 250 x 600 x 20 mm
blanks and then rolled down to 1 mm thick sheet. These hot-
rolled sheets were then used in mechanical and corrosion tests
and in weldability testso The most favourable heat-treatment
for these steels proved to be the following:

Influence of Molybdenum E073/E335
Heat A ... 800 0C/0.5 firs/air
it B ... 900 OC/0-5 hrs/air.
The mechanical properties of thus heat-treated steels do not
differ substantiall from the properties of semiferritic steels
containing 170,0' Cr (9SN 17041). After this heat-treatment,
both heats proved satisfactory in double-bending tests; in
Ericlisen tests both heats achieved the value of 7.9 mm.
Welding tests were carried out by are-welding in an argon
atmosphere; the weldability of Heat A was better than that
of Heat B. Potentiostatic polarisation curves were determined
to obtain information on the corrosion behaviour of the steels.
The following conclusions were reached: Additions of 29. Mo
and 20" Cu proved the most suitable. The resistance-to-corrosion
of steels with 17% Cr, 20.0' Mo and 2% Cu is higher than the
resistance-to-corrosion of the same type Of steel without Mo
and Cu. Very good results were obtained with steel containing
2556 Cr and an addition of Mo and Cu which, for most corrosive

media, will have the same resistance-to-corrdsion as the
austenitic CrNi steel CSN 17241. According to the achieved
results, the steel with the lower Cr content can be used for
lesslagressive corrosion media and in cases in which the
stee SN 17041 cannot be used owing to its lower resistance-to-
corrosion or its poor weldabillty. Steel with a higher Cr
ontent (Heat B) can be used as a substitute for the steel
N 17241 but the plasticity and weldability of this material
H
are not as good as those of. steel '6SN 17241.

TEXT: The article describes -.-he chemical composition, properties, and
weldability of ARM cast steels developed by the SVUMT for the temperatuva
range of 550 - 7000C, The ARM 10 - 12 steel types are modified IlAr stain-
less cast steels, suitable for temperatures of 550 - 600n-C, while types ARM

for temperatures above 6000C. The ARM 10 and 11 are both CrMoV steels, the
former suitable for larger, thick-walled castings, the latter (with a hiE7her V1

of the ARM 5 steel (similar to the Soviet TsZh 8 !6/13 steel with W, Mo,

heat resistance and weldability due to its higher (6%) W content, Welda-
b-i-11ty tests with CrNi steels were made according to the method developed
by K,V. Lyubovskiy. It was found that CzechoSIOTak E 891 and E 391 elec-
Trodes produce welded joints which are sufficiently heat-resistant at oper-
ating temperatures of 625 - 6500C, However, some structural elements, es-
pecially the ferrite content, must be closely controlled. According to
practical experience, the ferrite content in the first bead should range
from 2 - 5~lo when E 391 eloctrodea are used. J. Koutsk~, V. Pilous,

stainless, austenitic-ferritic Cr2lNi5Ti and CrMi.AWTi steels vhi~:h were
developed in th- USSH to replace the classical CrNi and Ti-stabilized steels

the domestic CSN 17 246 (Poldi AKVS) and CSN 17 347 (Poldi AJKV ExtrgSs)
steels, detailed mechanical and weldability tests wire made in the SR.
It was found that mechanical properties of these two-phase steels are strong-
ly dependent on the Hi content, and that plastic properties improve with V
increasing Ni content. Compared with the classical Crl8Ni8Ti and CrlHi9-
MoM steels, the ultimate strength and yield points are considerably higher,
ductility and notch toughness are somewhat lower, and anticorrosive proper-
ties are about the same. Weldine tests were made on l-, 3-, and 20-mm

electrQdes, and mechanical properties of the weld metal were determined.
Again, it was found that steels with higher Ni cuntent have better ductility
values, while steels with higher Mo content have somewhat lower ductilities,
due to a zone of hiL-her Cr-ferrite content in the weld metal. These differ-
ences in ductility and Erichsen cupping values are most likely attributable
to the total amount of austenite- and ferrite-,forming elements in the heat,
1~ e. heats with hibrber contents of theae additions (higher r-phase con-
tent) also have better ductility and cupping properties. There nre 2

absence of deficient Co and good weldability.

TCXT: The authors present a short review of literature on hardfacing
materials which do not contain Co and which, after additional heat treatment,
single out a strengthening 6~-phase. Experiments 6f the Czechoslovak Institute
of Materials and Techniques on the development of such an alicy for arc hard-
facing ar6 discussed. Austenite-forming C, 11, Ni counteract the separation of
the 6'-phase (Mn dissolves considerably in the 4!r-phase), ferrite-forming S1, and,
to a lesser degreo, Mo, Ti and Nb, promote its separation. Some variants of hard-

C 0.09, I-In 1.0, Si 5.0, Cr 17.0, Ui 7.9. The Institute in cooperation with the
"Moravskoalezsk4 armaturkall Plant carried out the hardfacing of some sets of
sealing parts for steam valves. The hardfaced valves operated satisfactorily
during tests on a high-pressure stand at 5000C and under particularly difficult

TEXT: To replace the widely used austenitic stainless Cr-Ni steel (9% NJ,

small amounts of it. The chemical composition of the steel (in %) is: C 0.05 -

sion resistance of the steel can be raised by addition of 3.5% NJ or 0.10 - 5.0%
Mo (or by joint addition of NJ and Mo). The mechanical properties are improved
by addition 'of B or Zr in a 0.05% amount, or by their simultaneous addition in a
quantity of 'up to 0.10%. The steel structure should not contain > 25% of t~e
ferritic component. The production of this steel has an economical advantage,
since its use makes it possible to reduce the weight of tha~castings (due to
improved mechanical properties) and their NJ content. Moreover, the wide-ranged

ABSTRACT: The advantages of low-carbon steel may be offset by the choice of
wrong production methods and by keeping it too long at critical temperatures
for the precipitation of carbides. Me paper discusses the kinetics of
precipitation of chromium carbide in two 40 kg batches of steel of type

growth; around 3,000 cal/mol in the nucleation area. The averaga chemical
composition of Me6 is Cr1q.8 F03.296 for the state of equIlbriume In the
nucleation area the precipitated carbide was substantially richer in iron,
whoroaa In the diffuvion-growth area the iron content declined due to the
inoreaaod rate of diffusion of the chromium. The distribution of total
carbon between mwtenite and carbides depends upon the carbon content above

i~ ferritic steels resistant to inter-crystal cdrrosion. These steels contajn from
30 to 50 percent ferrite, the remainder is austenite and type M2JC6 carbide. The
ferrite contains from 22-5 to 25% chrome, and from 3 to 5% nicke , and the aus-
tenite contains from 19.5 tp 22.5% chrome and from 5 to 6% nickel, with a total
contant of carbon in the alloy of up to .25%., a silicon content up to 1,0o', a 6%
manganese content by weight, and with the usual content of inclusions.

ABSTRACT: Three austenitic chromium-nickel steels were investigated

especially susceptible when solution heat treated at temperatues above
1050C. The 17 246 steel when annealed at 1300 or 1400C and then held for
20 or I min,respectivelyat 700C became susceptible to Latergranular
corrosion. The H7247 and AKV8 steels showed somewhat better behavior.
In titanium-stabilized steel a complex carbide, possibly (Ti. Fe. Ce)
(C, N), is formed at high annealing temperatures. During the sub-
:sequent sensitizing treatment at 700-800C, it decomposes, resulting
in concentration gradien'ta. In this condition the steel becomes
susceptible to Lntergranular corrosion. However, with prolonged
sensitizing treatmente the concentratioa gradients are leveled out and
a polyhedral carbide Ti(C, N) is formed; in its presence the
susceptibility to intergranular corrosion decreases. More or less
similar effects are expected to occur in niobium-stabiltzed steels.
GeneralLy, low-carbon, steel appears to be the least susceptible to
intergranular corrosion. Orig. art. has: It figures and 3 tables.

TITLE: Contribution. to the study of fractitte surfaces on stainless steels of the o"OD
type Crl8tjqT~i
SOURCE: Kovove materialy, no. 1, 1966, 0-73
TOPIC TAGS: stainless steel, annealing, -irbide, cor-osion, steel, material fracturO,

ABSTRACT: The paper describes some results of an investigation of the fracture Sur-
faces of type Crl8Ni9Ti steels performed by the electron microscopy method. in
the process, polarization curves in different electrolytes were determined, and the
chemical composition of the fracture surfaces was estimated. The differences in
morphology as well as in the rate of precipitation of the M23C6 carbides on the
boundaries of grains were identified. While the carbides were precipitated after
5 minutes of annealing at 750C on the boundaries y - 6, intensive precipitations
took place only after one hour of annealing on the boundaries y - y. This corres-
ponded to the state when the material develops a tendency to intergranular corrosion.
Selective dissolution of areas tending toward this corrosion can be attained in a
5 per cent formic acid electrolyte. The original amount of 18 per cent Cr was found
reduced to 10 per cent in the region of fracture. A small increase in nickel

co ntent was observed which, however, cannot prevent the starting of corrosion.
The results of investigation are'in accordance with the Rollason's curve fur the
steel investigated, and confirm the theory that the tendency to intergranular

corrosion of Crl8ffigTi steels is caused by the lowering of Cr content In the regions
,of grain boundaries after precipitation of M23C carbides. Orig. art. has: 13 fig-

ABSTRACT: The influence of the wall thickness of mechanical properties, on the
annealing temperature, andAthe time needed for annealing in the elimination of
intercrystalline corrosionlis investigated. Isothermal annealing at 7500C was
studied; long term heating to 600 - 700*C in materials with varying ratios of Ti : C
was investigated with respect to notch strength and the appearance of fracture
surfaces. When casting is made at 700 - 8OO'C the notch strength is decreased
significantly because of precipitation of carbides and of sigma 3ham, Orige art*

Abstract: The authors discuss three cases of invagination of the small in-
testine. They were caused by a fibroma. a lipoma and polyposis, respectively.
In adults, the disease is usually due to demonstrable pathological changes,
mostly tumors. The changes can be diagnosed by detailed passage examinations
and surgical removal of tumors might prevent the development of invagination.

Abstract; [Authors' HunL~,arian su;mmary] It is pointed out by the authors that,

A lon:-, loud systolic murmur above the apex, on the other hand, can be pre-

. without re7urgitation in cases of severe mitral stenosis. If a loud
murmur of aortic stenosis accom-imnies mitral stenosis, it does not always
indicate a severe case of aortic stenosis. A prolon.,,ed,loud systolic murmnur
above the pulmonary aorta can also occur in cases of mitral stenosis alone.
These observations are supported by sample case histories of one patient each.

Abstract: [Authors' Hungarian summary] On 4 patients, a total of 5 thoracic
sympathectomy (Smithwick-Telford) operations were performed. Three of the
patients underwent surgery because of occlusion of a main vessel; one had
Buerger's disease. By means of the original technique of thoracic sympathec-
tomy as recommendad by Smithwick, excellent results were achieved in every
case. The uniformly good result is considered to be a condition which must
definitely be taken into consideration when the indications for an eventual
reconstructive operation are set up. All 11 references are Western.
