42CrMo steel is a Chinese alloy steel, and has high strength and toughness, good hardenability, and no obvious temper brittleness. After quenching and tempering treatment, it has high fatigue limit and resistance to multiple impacts, and good low temperature impact toughness.
Applications
42CrMo alloy steel generally used for engineering steel purpose, and for making important parts requiring higher strength and larger size of the quenched section than 35CrMo steel, such as shafts, crankshafts, large gears for locomotive traction, supercharger gears, gearbox gears, engine cylinders, oil drill pipe joints, large load rods and spring clips.
