Description

Technical Parameters

42CrMo4 Moly Alloy Steel

42CrMo molybdenum 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. Used in the manufacture of 35CrMo steel requirements than the higher strength and tempering cross-section larger forgings, such as locomotive traction with large gears, supercharger transmission gears, pressure vessel gears, rear axle, loaded with a great deal of connecting rods and spring clamps, but also can be used for 2000m below the oil drilling rod joints and salvage tools and can be used for bending machine molds and so on.
