Wear-resistant steel plates consist of a low-carbon steel base and a wear-resistant alloy layer, which usually accounts for 1/3 to 1/2 of the total thickness. The base provides strength, durability, and plasticity, while the alloy layer provides wear resistance under certain conditions.
Wear-resistant steel plates are mainly divided into three categories: general-purpose, impact-resistant, and high-temperature resistant; the total thickness of wear-resistant steel plates can be as small as 5.5 (2.5+3) mm and as thick as 30 (15+15) mm; wear-resistant steel plates can be rolled into wear-resistant pipes with a minimum diameter of DN200, and can be processed into wear-resistant elbows, wear-resistant tees, and wear-resistant reducers.
Excellent wear resistance
The alloy wear-resistant layer contains 4-5% carbon and 25-30% chromium. More than 50% of its structure is Cr7C3 carbide, with a macro hardness of HRC56-62 and a chromium carbide hardness of HV1400-1800. This structure is perpendicular to the direction of wear, and the wear resistance is doubled compared to cast alloys with similar composition and hardness.

Good impact resistance
The base layer is made of low carbon steel or low alloy stainless steel, which has toughness and enhances the impact resistance of the material. The wear layer handles the wear, while the base layer supports the load, making it ideal for high impact environments such as material conveying systems.

Heat resistance
The alloy wear layer can withstand high temperatures up to 600℃, and adding vanadium or molybdenum can withstand high temperatures up to 800℃. The recommended operating temperatures are:
Ordinary carbon steel substrate: ≤380℃
Low alloy heat-resistant steel plate: ≤540℃
Heat-resistant stainless steel substrate: ≤800℃
Corrosion resistance
The alloy layer has a high chromium content and has anti-rust and anti-corrosion properties. It can be used for coal hoppers, funnels and other uses to prevent coal from sticking.

Processing capabilities
These steel plates can be cut, bent, welded, and stamped, and can be made into various parts like ordinary steel plates. Cut wear-resistant plates can be welded into engineering structures or components.

Functions and features
Wear-resistant steel plates can be welded and have excellent wear resistance. They provide strength, durability and versatility for a wide range of industrial applications.
