NM400 NM450 NM500 Steel Plate NM400 steel is a high-strength, wear-resistant steel known for its superior strength and rigidity. NM400 is a Chinese GB standard steel grade. NM 400 is widely used in industries where abrasion resistance is important, such as construction and mining. NM450 is a wear-resistant steel sheet with a hardness of 450 HBW. NM450 wear-resistant steel sheet has very good weldability. N - "wear-resistant" in the "resistance" of the first phonetic alphabet. M is "wear-resistant" in the "grinding" of the first phonetic alphabet.450 Brinell hardness HB value. (450 hardness is wide, domestic NM450 hardness value is about 450). NM500 steel is one of the steel grades in the GB 24186 standard. NM 500 steel is a high strength, wear/abrasion resistant steel known for its superior hardness and durability. This steel is specially designed to withstand high wear conditions and provide long service life in harsh environments. We can provide…
