Conclusions
-
1.
Tungsten and molybdenum increase the relaxation resistance of austenitic Cr−Mn steel containing at least 1 at. % V and 0.2 at. % Nb.
-
2.
Combined alloying sharply increases the relaxation resistance of Cr−Mn steel.
-
3.
Reducing C/N from 1:1 to 1:2 increases the relaxation resistance.
-
4.
The relaxation resistance of most of the austenitic Cr−Mn steels is not inferior to that of Cr−Ni steel 3Kh19N9MVBT (ÉI572) at 600°.
