NM400 wear-resistant steel

NM400 is a kind of wear-resistant steel with excellent wear-resistant properties. It is mainly used to manufacture wear-resistant parts, such as mining machinery, engineering machinery, metallurgical machinery, coal mining equipment, construction machinery, loaders, excavators, etc.

Chemical composition:
- The carbon (C) content is generally controlled between 0.30%-0.40%. The addition of carbon elements can improve the hardness and wear resistance of steel.
- Manganese (Mn) content is generally between 1.00%-1.50%. Manganese element helps to improve the strength and hardness of steel.
- Silicon (Si) content is generally between 0.30%-0.80%, which helps to improve the wear resistance and wear resistance of steel.
- Phosphorus (P) and sulfur (S) content are usually controlled at low levels to ensure the welding performance and formability of the steel.
- Other trace elements such as chromium (Cr), molybdenum (Mo), nickel (Ni), etc. may be added to improve the wear resistance and corrosion resistance of steel.

The development history of NM400 wear-resistant steel can be traced back to the background of increased demand for wear-resistant materials.
