1. Brief introduction
Wear-resistant steel plate refers to a special product specially designed for use in severe wear conditions. At present, the widely used wear-resistant steel plate is made by welding a certain thickness of alloy wear-resistant layer with high hardness and excellent wear resistance on the surface of ordinary low-carbon steel or low-alloy steel with good toughness and ductility. In addition, there are cast wear-resistant steel plates and alloy hardened wear-resistant steel plates.



The wear-resistant steel plate consists of two parts: a low-carbon steel plate and an alloy wear-resistant layer. The alloy wear-resistant layer generally accounts for 1/3 to 1/2 of the total australia number data thickness. During operation, the matrix provides comprehensive properties such as strength, toughness and ductility to withstand external forces, while the wear-resistant alloy layer provides wear resistance that meets specified working conditions. The thickness of the wear-resistant alloy layer is 3-20 mm.

There are two types of wear-resistant steel plates popular in the market: wear-resistant composite steel plate and NM wear-resistant steel plate. Typical examples include NM360 wear-resistant plate, NM400 wear-resistant plate, NM500 wear-resistant plate, etc.



Wear-resistant steel plate is also known as quenched and tempered steel plate after quenching and hardening in the rolling process or after quenching and hardening heat treatment of low alloy steel plate. The hardness is generally within the range of HB350-500.
