Introduction of 30CrNiMo8 alloy steel

30CrNiMo8 has high yield strength, tensile strength and fatigue strength, as well as sufficient plasticity and toughness. Generally, electric arc furnace and oxygen top-blown converter are used for smelting. If it needs to be with more higher requirements. It is made by the external furnace refining, electroslag remelting or vacuum processing, vacuum induction furnace smelting or double vacuum smelting, and appropriate heat treatment.

How about the 30CrNiMo8 application?

30CrNiMo8 steel has a wide range of uses.It is not only used on the high pressure chemical tanks with high pressure and frequent fluctuations. But also used in pressure pipes, plastic molds, and important structures.

It is an alloy structural steel. It is used in engineering structures such as high-strength shafts, bolts and nuts, gears and spindles. Locomotive traction gears, supercharger transmission gears, pressure vessels, rear axles, connecting rod gear loads and spring clips. 30CrNiMo8 can also be used for oil drill pipe joints and fishing alloys below 2000 meters deep wells, for bending machine molds.It is for permanently stressed components with large cross sections for automotive and mechanical engineering.
