NM550 is a high-strength wear-resistant steel plate. The “NM” in its name represents the initials of the Chinese pinyin for “耐磨” (NaiMo, meaning wear resistance), while “550” indicates that the average Brinell hardness value of this steel plate is approximately 550 HBW.

NM550 steel plate complies with the GB/T 24186-2022 standard. It possesses excellent mechanical properties and wear resistance, and is widely used in occasions or parts requiring wear resistance. This application helps prolong the service life of equipment and reduce downtime and financial investment caused by maintenance.
