Generally speaking, the higher the hardness of the steel plate, the more wear resistant, so 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?
At present, the common higher hardness steel plates are divided into the following categories:
1. High manganese steel sheets, 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 have severe impact or large pressure in order to make the surface work hardening to show its high wear resistance, otherwise the high manganese wear resistant steel is not wear resistant. Commonly used in shot blasting machines, ball mills, pulverizers and other parts that are easily worn by strong impact.
2. Wear resistant ferrochromium steel plates, 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 low alloy steel plates after heat treatment, 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 plate has excellent comprehensive properties and is widely used in construction machinery, construction machinery, port machinery, mining machinery, cement machinery, Metallurgical machinery and thermal power plants and other industries.
In daily production and life, the choice of wear resistant steel plate should be selected according to the actual working conditions. The wear resistant steel plate can exert the best wear resistance under suitable working conditions, not just looking at the hardness.
