AISI 4140 Round Steel Bar 

AISI 4140 steel, this steel has good workability, small processing deformation, good fatigue resistance, is a medium hardenability steel, 4140 has good strength and good comprehensive mechanical properties after heat treatment, good workability, yield High. The maximum use temperature is 427 degrees Celsius. 4140 strength, high hardenability, good toughness, small deformation during quenching, high creep strength and lasting strength at high temperature. 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.
