Mechanical properties of wear-resistant steel
Basic information
It is a special structural steel with high wear resistance. Generally speaking, the higher the hardness, the higher the wear resistance. This kind of wear-resistant special structural steel has an average hardness of B. After quenching, or quenching and quenching, it has a good martensite-bainite microstructure. The addition of molybdenum, nickel, and boron alloys ensures uniform texture throughout the thickness direction.
Uses
Used for wear-exposed structures, such as protective pads and shell walls of prospectors and bulldozers. Cut panels to support or stiffen the overturned body of a truck. Wear plates for mixing and conveying elements, chute trenches, displays, machine tools, crushers and shredders, waste briquetting presses, blades, paving grinding tools and agricultural machinery.
