Steel NM
Wear-resistant sheets NM (analogue of Hardox )
NM grade sheet metal is a wear-resistant steel sheet with fairly high mechanical strength. Its mechanical properties are 3-5 times higher than those of conventional low-alloy steel plates, which helps to significantly increase the strength of mechanical parts.
Wear-resistant steel grade NM is widely used in the manufacture of equipment, parts and mechanisms operating under conditions of abrasive environments, strong friction and intense mechanical loads: in underground mines, the cement industry, road construction, mining and open-pit mining and metallurgical industry and production, industrial and agricultural engineering, etc.
Standard – GB/T24186-2009
