Description
NM400 Wear Resistance Steel Plate
NM400 Wear Resistant Steel Plate is a high-performance abrasion resistant steel widely used in heavy-duty industrial applications where severe wear and impact occur. This grade is specifically engineered to deliver excellent resistance against sliding abrasion, friction, and mechanical wear caused by materials such as ore, gravel, coal, sand, and minerals.
NM400 steel plates are manufactured using advanced quenching and tempering processes that enhance hardness and toughness. With a typical hardness of 400 Brinell Hardness Number (BHN), NM400 plates provide superior wear resistance compared to conventional carbon steel and structural steel grades.
The UNS designation commonly associated with wear resistant steel similar to NM400 is UNS K40000, representing high hardness abrasion resistant steel used in mining, construction, and heavy industrial equipment.
