Features And Usage Of NM400 Steel Plates

NM400 is one kind of Chinese wear/abrasion resistant steel plates, which is well received in middle east and Africa. An NM400 wear-resistant steel was hot rolled and then the plates were heat-treated by direct quenching and tempering and reheat quenching and tempering techniques, respectively.

NM400 Abrasion Resistant Steel plate

NM400, NM means wear-resistant, 400 means the average Brinell hardness is about 400. Liangang NM400 is widely used in the metallurgical industry, road construction industry, sand mill barrel, blades, U-type dump trucks, various freight yards, dock machinery parts, bearing structures, railway wheel structures, rollers, etc. The defects such as bubbles, cracks and looseness formed in the pouring process of NM400 wear-resistant plate can also be eliminated under high temperature or high pressure to restore its excellent quality. Standard classification of NM400 wear-resistant plate: Submerged arc welding NM400 wear-resistant plate is used for pressurized fluid transportation and is mainly used for oil and natural gas pipelines; wear-resistant plate has the advantages of leading technology, mature production process and large market share in the world. Looking at the classification of wear-resistant steel plates, the product types under wear-resistant steel plates can be divided into NM400, NM450, NM500, NM550, and NM600 according to their respective hardness.
