What is AR450 equivalent steel in China

According to hardness and welding process, the main steel grades of wear-resistant plate are NM360, NM400, NM450, NM500, NM600 in China. Among them, NM450 is AR450 equivalent steel. “450” represents the average Brinell hardness of NM450 steel plate.

AR450 equivalent steel NM450 is high-strength wear-resistant steel. NM450 steel plate is mainly used to provide protection in the places or parts where wear-resistant is required, so as to prolong the service life of the equipment, reduce the maintenance and shutdown brought by maintenance, and correspondingly reduce the investment of funds.

AR450 equivalent steel NM450 wear-resistant plate is widely used in mining machinery, coal mining machinery, environmental protection machinery, engineering machinery, etc.. It is also commonly used as high-strength structural steel with yield strength ≥ 850MPa.
