42CrMo steel

Posted:2018-07-19 15:53:25

42CrMo steel is an ultra-high strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, and good low temperature impact toughness. The steel is suitable for the manufacture of large and medium-sized plastic molds requiring a certain strength and toughness.
