Conclusions
-
1.
Silicon (0.3–1.5%) and nickel (0.10–3.3%) have a negligible effect on the hardenability of die steels of the 4Kh4VMFS type. The susceptibility of such steels to overheating increases notably with the nickel concentration but hardly varies with increasing silicon concentrations.
-
2.
Alloying die steels of the 4Kh4VMFS type with nickel* is inexpedient, since it does not improve the plasticity or impact toughness at 20°C and leads to a sharp reduction of heat resistance and strength at elevated temperatures.
