Describe

4140 steel belongs to medium hardenability steel, which has the advantages of high yield, good comprehensive mechanical properties, good strength, good toughness and high hardenability. Its carbon content is 0.33%-0.48%, its tensile strength is 795 MPa, and its hardness is It is 241HB

Advantage

After heat treatment, 4140 has good strength and good comprehensive mechanical properties, and has good manufacturability. It can be used to make steam turbine fasteners, salvage tools, etc.

Feature

This steel has good strength, good toughness, high hardenability, good workability, small processing deformation, quite good fatigue resistance, small deformation during quenching, high creep strength and durable strength at high temperature and so on.

Application

It is used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and spring clips that are heavily loaded, and can also be used for Drill pipe joints and fishing tools for oil wells below 2000m, and can be used for molds of bending machines, etc.
