42CrMo steel is a ultra-high-strength steel, has high strength and toughness, has good quenchability, has no obvious ignition brittleness, has high fatigue limits and anti-multiple impact capabilities after quality adjustment treatment. The low temperature impact toughness is good. The steel is suitable for large and medium-sized plastic molds that require a certain strength and toughness.
