Description and Application
4140 steel pipe has high strength, hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperatures. 4140 material is mainly used for forgings requiring higher strength and larger quenching section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, extremely loaded connecting rods and spring clips, can also be used Oil deep well drill pipe joints and fishing tools below 2000m.

4140 Steel Pipes Characteristics
4140 steel pipe has good processability, small processing deformation, and good fatigue resistance. It is a medium-hardened steel. It has good strength and good comprehensive mechanical properties after 4140 heat treatment. It has good manufacturability and high yield. The maximum use temperature is 427 degrees Celsius. 4140 strength, high hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperatures. Forgings requiring higher strength and larger quenching section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, extremely loaded connecting rods and spring clips, can also be used Oil deep well drill pipe joints and fishing tools below 2000m, and can be used for molds of bending machines.
