30CrNiMo8

30CrNiMo8 is an alloy steel belonging to the group of nickel-chromium-molybdenum steels. It is a high strength, high toughness steel commonly used in the manufacture of heavy machine parts such as gears, crankshafts and axles. The addition of nickel and molybdenum gives 30CrNiMo8 its high strength and toughness, while the carbon content provides good wear resistance and machinability. This steel is usually supplied in the quenched and tempered condition, meaning it is heat treated to improve its properties. 30CrNiMo8 is known for its excellent mechanical properties, including high tensile strength, high yield strength and good fatigue resistance.
