Introduce

31CrMoV9 is a nitriding steel which has at least 2.3%Cr,0.15%Mo,0.1%V as strengthening alloy elements.

Due to its high wear resistance,it is mainly used in the automotive industry and general components mechanical engineering.30CrMoV9 is difficult to weld and therefore should not be used in weld constructions.It can attain surface hardness of 800 HV after nitriding.

Applications

With its high wear resistance 1.8519 steel is used widely in the engineering and automotive industries. Suitable for components with medium and large cross sections which require high tensile strength and good toughness. Typically used for in gear and engine construction for components such as crankshafts, connecting rods, steering knuckles, screws and bolts.
