Wear-resistant plates are chemically composed of carbon, manganese, phosphorus, chromium, sulfur, silicon, molybdenum, nickel, and boron. The presence of these chemical components improves the ability of the plate to reduce the wear and tear on the surface of the instruments used in mining, construction, agriculture, earth-moving machinery, dump truck bodies, and conveyor belts. Wear plates have high carbon content which enhances the hardness of the steel making it abrasion resistant. The chemical composition of the wear plate improvises the tensile strength, and its ductility as well as creates a positive impact on the corrosion resistance factor.The chemical composition of AR300, AR400, AR450, and A500 is given as below
