30CrNiMo8

30CrNiMo8 is an alloy steel that belongs to the nickel-chromium-molybdenum steel group. 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 a quenched and tempered condition, which means 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. It is also known for its good weldability, which makes it suitable for use in welded structures.

Overall, 30CrNiMo8 is a high-quality steel that is widely used in various industries with high requirements for strength, toughness and durability.
