What are the mechanical properties of 30CrMo steel?

30CrMo steel is a Chinese alloy steel used in engineering and mechanical structures. It has high strength and high toughness, and has good high temperature strength below 500°C. 30CrMo material also has good machinability, medium cold bending plasticity, high hardenability, and good weldability. It is generally used in an adjusted state.

30CrMo alloy steel can be used to manufacture steel pipes whose working temperature is below 400℃, for fasteners whose working temperature is below 450℃ for boilers and steam turbines, and to manufacture high-pressure nuts and flanges whose working temperature is below 500℃. General mechanical load; shafts, gears, bolts, studs, manipulators, high-pressure pipes and welding in chemical equipment below 250°C, working with nitrogen-hydrogen media.
