SOVIET METALLURGY DEVELOPS NEW TYPES OF ST=.
LENINGRAD PLAN: DEVELOPS TURBINE STEEL -- Leningradskaya Pravda, 9 Feb 52
During 1951, the Leningrad Plant imeni Lenin received two large special
the orders other for for steel casting: one for hydroturbines of the Taimlyanskaya- OES and
a new type of steel to be used in a special 150,000kilowatt
steam turbine. For this kind of turbine, special cast steel parts were re-
quired that can operate at far higher temperatures than regular steam turbines.
Modern technology has developed types of steel which are extremely heat-
proof. However, in thx case current types of steel were not adequate, as they
were intended for machines with a relatively short Service period. In the case
of parts for a turbine with an extra high capacity, the steel had to be not
only extra strong, but also creep--esistant when operating at high temperatures
and under heavy loads. To increase the turbine efficiency, the clearances be-
tween rotating and stationary na-+o ore reduced to a minimum. Therefore, in
the case of metal deformation. due tc rcreep, sme of
ub against others, and because of the tremendous operating parts are theety to speed they would be in danger of break:ng. Similar cases have repeatedly been observed'
in foreign countries.
It was necessary to develop new tyr,ss of steel and to test all of their
properties. Numerous experiments were made at the Plant imeni Lenin in coopera-
tion with scientific research workers. An analysis of experimental research
shoved that two methods could be used to obtain the required type of steel:
o
ne was to raise the total amount of alloying elements and at the same time use smal
only a
number of elements to increase the number of alloying elements and determine
at the same ptim1e reducetthe'totalo
content of such elements. The second method is more difficult to use in steel-
smelting plants, but also more economical. After careful consideration, it was
decided to employ the second method.
