NM400 high strength steel plate

NM400 is a kind of wear-resistant steel plate. NM – represents wear-resistant use of “resistant” and “grinding” Chinese pinyin first letter 400 is the Brinell hardness value HB value. (The hardness value of 400 is generalized, and the hardness value range of domestic NM400 is 360-420.)

The NM400 steel plate has quite high mechanical strength; Its mechanical properties are 3 times to 5 times that of ordinary low alloy steel plates.

Wear Resistant Steel Grade:
NM300,NM360,NM400,NM450,NM500,NM550,NM600

Wear Resistant Relative steel grades:
