What are the applications of 42CrMo seamless steel pipe? In order to better understand the applications, we should have a good learn of the chemical composition and mechanical properties of 42CrMo seamless steel pipe.

Chemical composition of 42CrMo seamless steel pipe: C: 0.38-0.45, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.90-1.20, Mo: 0.15-0.25, V: 0.15-0.30.

Mechanical properties of 42CrMo seamless steel pipe: tensile strength: 1080 MPa, yield strength: 930 MPa, elongation after fracture: 12%, reduction of area: 45%, impact energy: 63J.

Main characteristics of 42CrMo seamless steel pipe:
Due to the effect of carbon and chromium content, 42CrMo seamless steel pipe has better strength and hardenability, higher fatigue strength and resistance to multiple impact after modulation, good impact toughness at low temperature and no obvious temper brittleness. It is generally used after quenching and tempering.

Application of 42CrMo seamless steel pipe:
42CrMo seamless steel pipe is generally used to make important parts with high strength and large section size, such as shaft, gear, connecting rod, transmission gear, supercharger gear, engine cylinder, spring, spring clip, 1200-2000mm oil drill pipe joint, etc.
