Steel Types According to GOST Specificiations
Special-Purpose Steel Types
Railroad steel
Further sheets on tool steel and special-quality steel types are in
preparation, and will be added to this list as soon as production of them
becomes feasible.
A temporary, arbitrary list of special-quality types which have already
been produced is given on sheet 11.
Special sheets are being prepared listing those types of steel which are
being produced in plants not belonging to the Main Department for Metallurgy.
The Index List of Steel Types of the Min Department for Metallurgy of
the Ministry of industry contains those steel types which are being produced
in the German Democratic Republic at present. Steel types not listed in the
index are not being produced. In exceptional cases the amain Department for
Metallurgy can awake a. decision, after checking with the Iron Research Insti-
tute (Corporation of Public Law), Hennigsdorf, on production possibilities.
DIN specificiationg were the basis for the index List of Steel Types.
To supplement this list, types on the SEL (Steel-Iron List), the specifica-
tim for which conform with those of the norm DIN 17006, are also given.
Types given in parentheses in the "DIN" and "SSL" columns are those for which
the designations given do not conform fully with both sets of specifications.
Analysis values given in parentheses in the "Composition" column indicate that
these either are not container', in the DIN specifications or do not conform to
them. The analysis values in parentheses are valid as basic values for the
steel mill, but not in regard to acceptance.
M Open hearth steel
T -- Thomas steel
Ts - Thomas steel, special quality
E -- Electrosteel
b -- Killed steel (beruhigt)
u -- Rimmed steel (unberuhigt)
Abbreviations in the column "Producing Plant," which indicates the
enterprises of the WR Vest; (Federation of People-Owned Iron and Steel
prises), are as follows.
H -- Hennigsdorf
R -- Riess
H -- Mexhuette
G -- Groeditz
D -- Doehlen
