Product Description

Chemical composition of 30CrNiMo8

The chemical composition of 30CrNiMo8 contains 0.26-0.34% carbon content. The Mn content of the material is 0.5-0.8%, which gives the material a hardness. The content of P is reduced to 0.025% and S to 0.035% max, because excessive P and S will damage the quality of the steel and may cause the alloy steel to break under low stress. There is a high chromium content of 1.8-2.2%, which adds additional yield and stretching during heat treatment.

30CrNiMo8 Application

Due to its high hardness, 30CrNiMo8 is often used to produce high-end mechanical parts. In addition to manufacturing screws, robotic arms, pistons, shafts and shafts, 30CrNiMo8 can also be used to manufacture mechanical components. Due to its alloy steel content, 30CrNiMo8 can achieve high tensile strength. High temperature can be used for processing 30CrNiMo8. Under normal circumstances, 30CrNiMo8 material is used in the case of greater product wear. The oil and gas industry, aviation, mechanical engineering, chemical industry and shipbuilding all deal with corrosion issues, making 30CrNiMo8 a very useful material.
