NM400 is a type of wear-resistant steel plate. “NM” stands for the Chinese pinyin initials of (meaning wear-resistant) and (meaning abrasion). The number 400 refers to the Brinell hardness (HB) value, which, in this context, generally ranges from 360 to 420 for domestic NM400.

NM450 steel is a high-strength, wear-resistant steel plate with an average Brinell hardness of 450 HBW. Its mechanical properties are 3 to 5 times those of ordinary low-alloy steel plates, with a yield strength above 950 MPa and tensile strength around 1180 MPa.

NM500 steel is a high strength wear resistant steel plate designed to provide excellent mechanical properties and superior wear resistance. It is often used in industries that require high impact and wear resistance, such as mining, construction and industrial machinery, and is more cost-effective than bulletproof steel AR500.
