X45NiCrMo4
1.2767High-toughness nickel-alloyed tool steel for plastic molds and cold work applications. 4% Ni provides exceptional impact toughness at hardness levels of 48–54 HRC. Through-hardening up to very large cross sections. Used for injection mold frames, blow mold inserts, cold stamping tools requiring high toughness, tire molds and machine knives. Polishable to mirror finish. Can be nitrided for improved surface hardness.
