What are the features of 42CrMo alloy?

42CrMo steel plate is an ultra-high strength alloy steel plate with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, good low temperature impact toughness. This alloy is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness.
42CrMo alloy has high creep strength and endurance strength at high temperature. The steel usually uses surface quenching after quenching and tempering as a heat treatment scheme. As a plastic mold steel, it has excellent machinability and good mechanical properties.
 

42CrMo alloy features and scope of application

42CrMo alloy steel plate has high strength, hardenability, good toughness, small deformation during quenching, high creep strength and long-term strength at high temperature. 42CrMo alloy is mainly used to manufacture forgings that require higher strength and larger quenched and tempered cross-sections than 35CrMo alloy, such as large gears for locomotive traction, supercharger transmission gears, pressure vessel gears, rear axles, highly loaded connecting rods and spring clamp. It can also be used in oil deep well drill pipe joints and salvage tools below 2000m, and can also be used in bending machine molds.
