Conclusions 1. Alloying of steel R3M3F2 with nickel to 3.4% lowers the hardness after quenching, reduces the secondary hardness and red hardness somewhat, and increases the ultimate bending strength and resilience. To improve the mechanical properties of a tool operating under dynamic loads, it is possible to alloy this steel with nickel to 1.5%; in other words, the effect of nickel on the properties of the steel is analogous to a reduction in quenching temperature. 2. When up to 2.7% of manganese is introduced to steel R3M3F2, the secondary hardness remains virtually unchanged, and the red hardness is increased somewhat; these properties diminish sharply as the manganese content is increased. The ultimate bending strength is increased with a manganese content to 1.5%, and diminishes when its content is increased. 3. The introduction of copper to steels R3M3F2 and 11M5FYuS is inexpedient.
