Conclusions
-
1.
In tempering of 34KhN1M steel, types M7C3 and M23C6 carbide are formed.
-
2.
A reduction in carbon content in the steel causes an increase in the rate of the carbide reactions M3C→M7C3 and M3C→M23C6.
-
3.
There is a correlation between the hardness of 34KhN1M steel and the degree of development of the M3C→M7C3 carbide reaction. With development of carbide transformation a reduction in hardness of the steel is observed.
