42CrMo4 Material Introduction


Is used to manufacture forgings with higher strength and larger cross-section than 35CrMo steel, such as big gear for locomotive traction, turbocharger transmission gear, rear shaft, connecting rod and spring clamp with great load.


42CrMo4 can also be used for drilling pipe joints and fishing tools in deep oil Wells below 2000m.


Executive standard :EN 10083/3-2006


Similar material: 42CrMo, 708M40, 4140


42CrMo4 Characteristics:


Has high strength, hardenability, good toughness, small deformation during quenching, high creep strength and endurance strength at high temperature.


42CrMo4 steel is an improvement of American AISI standard 4140 steel. The steel has good machinability, easy polishing, easy to bite and can be electroplated.


42CrMo4 alloy steel(Bar,Plate,Square) is suitable for large and medium sized plastic molds which require certain strength and toughness.
