Nm400 Nm500 Nm600 Wear Resistant Steel Plate

The bimetallic composite steel plate is composed of two parts: low carbon steel plate and alloy layer, and the anti-wear layer generally accounts for 1/3-1/2 of the total thickness. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the layer provides performance to meet the requirements of working conditions.

Product Introduction

Hardness difference

The hardness value of nm400 steel plate is about 360-420.

The hardness value of NM500 wear-resistant plate is about 500.

NM600 wear-resistant plate hardness value in 580-625,

the hardness level is not the same NM600 hardness is higher, more wear-resistant and more expensive.
