Generally speaking, the harder the steel plate, the more wear-resistant it is. Therefore, the hardness value is often used as one of the important indicators to measure the wear resistance of steel plates.

At present, the common steel plates with higher hardness are divided into the following categories:
High manganese steel plates, such as high manganese steel (ZGMn13), high manganese alloy (ZGMn13Crmn), ultra-high manganese alloy (ZGMn18CR2MoRe), etc. It must be noted that high manganese wear-resistant steel plates must be subjected to severe impact or high pressure to produce work hardening on the surface and show its high wear resistance, otherwise high manganese wear-resistant steel is not wear-resistant. It is often used in shot blasting machines, ball mills, crushers and other parts that are easily worn by strong impact.

Anti-wear chromium iron steel plate, such as high, medium, and low chromium alloy cast iron (Cr15MOZCu), etc. It is often used in ball mills, cement mills, and crusher jaws.

Wear-resistant steel plates, such as heat-treated low-alloy steel plates: NM400, NM450, NM500, etc. Based on its inherent characteristics of high hardness, high strength, high toughness, low carbon and low alloy, low-alloy wear-resistant steel plates have excellent comprehensive performance and are widely used in engineering machinery, construction machinery, port machinery, mining machinery, cement machinery and thermal power plants.
