Product Description
42CrMo4 Steel Plate/Flat
1: 42CrMo4 Steel Introduction
42CrMo4 steel belongs to the ultra-high strength steel, with high strength and toughness, hardenability is also good, no obvious tempering brittleness, tempering treatment has a high fatigue limit and resistance to multiple impacts, low temperature impact toughness is good. The steel is suitable for the manufacture of large and medium-sized plastic molds requiring certain strength and toughness. Strength, high hardenability, good toughness, quenching deformation is small, high temperature has high creep strength and enduring strength.
