Nm400 Wear Resistant Plate

nm400 Wear Resistant Plate

NM400 is a kind of wear-resistant steel plate. NM- denotes the "resistant" and "abrasive" characters for wear resistant uses. The first letter 400 is the Brinell hardness value HB value. (400 hardness value is generalized, domestic NM400 hardness value range of 360-420.)

NM400 wear-resistant steel plate is widely used in construction machinery, mining machinery, coal mine machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, edge plate, side edge plate, blade. Crusher lining plate, blade

The delivery status of wear-resistant steel plate is divided into: tempering (i.e. quenching and tempering)
