Material round steel material: 42CrMo,GB/T 3077-1999
42CrMo steel is ultra-high strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and resistance to multiple impacts after quenching and tempering, good low temperature impact toughness. The steel is suitable for the manufacture of large and medium-sized plastic molds that require a certain strength and toughness.
High strength, high hardenability, good toughness, low deformation during quenching, high creep strength and long-lasting strength at high temperatures. Forgings requiring higher strength and larger quenching section than 35CrMo steel, such as locomotive traction Gears, supercharger gears, pressure vessels, rear axles, for load, for, for, for, and for, and, and
42CrMo steel has high strength and toughness, good hardenability, no obvious temper brittleness, small deformation during quenching, high fatigue limit and resistance to multiple impacts after quenching and tempering, good low temperature impact toughness, High creep strength and long-lasting strength at high temperatures. The steel usually has a quenched surface after quenching and tempering as a heat treatment scheme.
