Conclusions
-
1.
Additions of silicon and manganese to steel 100Kh13M cause a considerable reduction of the sulfur content in the solution (by a factor of 1.5).
-
2.
When steel 100Kh13M contains both manganese and silicon, the sulfur content of equilibrium with the exess phase decreases, and this causes an increase of the weight of the sulfide inclusions in the steel.
-
3.
The most efficient way of reducing the amount of sulfide inclusions in steel 100Kh13M is to reduce the sulfur content to 0.002–0.003%.
