NM500 steel is one of the steel grades in the national standard GB 24186.NM 500 steel is a high-strength, abrasion/corrosion-resistant steel known for its excellent hardness and durability. This steel is specifically designed to withstand high wear conditions and extend service life in challenging environments.With a hardness range of 470-540 HBW, NM500 is used in a wide range of applications where abrasion resistance is a major consideration, such as mining equipment, construction machinery and other heavy-duty applications.NM500 wear-resistant steel is more than three times stronger than ordinary low alloy steel plate, and wear resistance can be increased by 2-3 times, greatly extending the wear resistance of the steel. NM500 steel is more than 3 times stronger than ordinary low alloy steel plate, and the wear resistance can be 2-3 times higher, which greatly extends the service life of the steel plate.
