Characteristic: 42Cr2Mo steel tube is ultra-high strength steel, with high strength and toughness, its’ hardenability also good, no obvious temper brittleness, quenching deformation, quenching and tempering treatment has a higher fatigue limit and anti-impact ability, Low temperature impact toughness is good, it has high creep strength and lasting strength under high temperature, .

Application:42Cr2Mo alloy steel tube is usually quenched and tempered as a heat treatment solution. Used to manufacture more than 35CrMo steel strength and higher quality of the section of the forgings, such as locomotive traction with a large gear, supercharger transmission gear, pressure vessel gear, rear axle, by the load of great connecting rod and spring clip , Can also be used for 2000m below the deep well drill pipe joints and salvage tools, and can be used for bending machines and other molds.
