NM400 is a kind of wear-resistant steel plate.NM-indicates the wear-resistant use of the word "resistant" and "grinding" the first letter of the hanyu pinyin 400 is the Brinell hardness value of HB value. (400 hardness value is broad, domestic NM400 hardness value range 360-420.)
NM400 wear-resistant steel plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, edge plate, side edge plate, blade. Crusher liner plate, blade.
Wear-resistant steel plate delivery status is divided into: tempered (i.e. quenched and tempered)
Mechanical properties: hardness range: 360~440
NM400 wear plate is a high-strength wear-resistant steel plate, which has a high wear resistance, Brinell hardness value of 400 (HBW) is mainly in the need to wear-resistant occasions or parts of the protection, so that the equipment life is longer, reduce maintenance brought about by overhaul and downtime, and accordingly reduce the investment of funds.
Wear-resistant steel plate has high wear resistance and good impact performance is good, can be cut, bent, welded, etc., can be taken to weld, plug welding, bolting and other ways to connect with other structures, in the maintenance of the site process has a time-saving, convenient, etc., is widely used in metallurgy, coal, cement, electric power, glass, mines, building materials, masonry, etc., and other materials, compared to other materials, has a very high price-performance ratio, has been Favoured by more and more industries and manufacturers.
