GB NM450 Wear Resistant Steel
NM450 is a special structural steel with high wear resistance, generally speaking, the higher the hardness, the higher the wear resistance. The average hardness of this wear-resistant special mechanism steel is 450HBW, and after quenching or quenching and tempering, it has a good martensitic-bainite microstructure.
NM450 wear-resistant plate main scope of use:
Construction machinery: cement pusher tooth plate, concrete mixing floor, mixer lining board, dust collector lining board, brickmaking machine mold board, etc.
Construction machinery: loader, bulldozer, excavator bucket plate, side blade plate, bucket bottom plate, blade, rotary drilling rig drill pipe, etc.
Mechanical properties of NM450 wear-resistant plate：
carbon equivalentCEV= C+Mn/6+(Cu+Ni)/15+(Cr+Mo+V)/5
