Characteristic:
4140 steel, this steel has good workability, small deformation, good fatigue resistance. It belongs to medium hardenability steel. After heat treatment, 4140 has good strength and good comprehensive mechanical properties, good processability and high yield. The maximum service temperature is 427 ºC. 4140 has high strength, hardenability, good toughness, small deformation during quenching, and high creep strength and rupture strength at high temperature. It can be used to manufacture forgings with higher strength and larger quenched and tempered section than 35CrMo steel, such as big gear for locomotive traction, transmission gear for supercharger, rear shaft, connecting rod and spring clip with great load, as well as drill pipe joint and fishing tool for oil deep well below 2000m, and bending machine.
