Generally speaking, the higher the hardness of 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 the steel plate. So, what kind of steel plate is the most wear-resistant?
Currently, common steel plates with higher hardness are divided into the following categories:
1. High manganese steel plate, such as high manganese steel (ZGMn13), high manganese alloy (ZGMn13Crmn), ultra-high manganese alloy (ZGMn18CR2MoRe), etc. It must be noted that the high manganese wear-resistant steel plate must be subject to severe impact or large pressure before the surface can be work-hardened and show its high wear resistance. Otherwise, the high manganese wear-resistant steel plate will not be wear-resistant. It is often used in shot blasting machines, ball mills, pulverizers and other parts that are easily worn by strong impact.
2. 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.
3. Alloy wear-resistant steel plates, such as heat-treated low alloy steel plates, JFE-EH400, JFE-EH500, DILLIDUR 450, 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 properties and are widely used in engineering machinery, construction machinery, port machinery, mining machinery, cement machinery, etc. Metallurgical machinery and thermal power plants and other industries.
In daily production and life, the selection of wear-resistant steel plates should be based on actual working conditions. Wear-resistant steel plates can exert the best wear resistance under appropriate working conditions, and it is not just about hardness.
