The wear-resistant steel plate is composed of low-carbon steel plate and alloy wear-resistant layer. The wear-resistant 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 against external forces, and the wear-resistant layer provides wear-resistant properties that meet the requirements of specified working conditions.

Pressure vessel steel plate, refers to the carbon steel and low alloy steel plate used to manufacture the pressure vessel shell.
