New Welding Alloys
1. During the latter part of 1952, Elektrochemisches Kombinat ;Eitterfeld (EKE)
developed a number of new high grade, heat resistant, welding alloys for
use under conditions of heavy stress (b. g. valve heads and seats, internal
combustion engines.).
2. -A ..alloys developed were tested under both are and electric welding
conditions. Particular attention was paid to the effect of the welding
-process since all the alloys tested were not "Stellite" but had ferrous
chrome bases of varying carbon content.
3. For loser temperatures and less. exacting conditions;) a second series of

as with a nickel chrome basis. For temperatures up to
~ chrome, alloys with ao.0.1 0.2% carbon content were produced.
These, though relatively soft, have the advantage that the prebiaeting
temperature of the parts. to be welded can be kept fairly low.
Details of the alloys developed are as follows:
F 28 S la:
1.6% carbon.
28% % chromium., 70.4% iron
F 28 SH lb:
2.2% carbon,
28% chromium, 69.8% iron

F 28 SHj, which contains 2% silicon is used in electric welding only
and can withstand temperatures of up to 12000, F 20 SD is difficult
to weld because of the formation of scoria, but has a high fluidity
and is specially suitable for use in welding hard metals.
6. EMB delivers 90 tons of these alloys monthly. Orders are received for
approximately double this quantity but cannot be met because of
shortages of chromium.
Experiments are also being made at Bitterfeld in the use. of molybdenum
as a substitute for i c hromium.
8. Blrasol, previously reported as a synthetic detergent, has now been
discovered to be a flux for light alloys.
Other_FEoduction
Aluminum
9. Output averaged 95 tons of pure aluminum per day during November and the
first half of December.
Tittiwn
10. No pure titanium was produced, but a certain amount of Ti 02 was produced.
B um
11. Output ceased during November because of the lack of raw materials.
Tungsten
12. The north factory at Bitterfeld processes tungsten ore of Chinese origin.
Output is absorbed. mainly by the East German light bulb and radio industry.
Cast Iron
13. Dr. Seeliger (fnu), a scientist employed at Bitterfeld, developed a new
cast iron whose tensile strength is claimed to be equal to that of
mild steel.
