product presentation
The working layer contains fine intercrystalline graphite, and the size, shape, and distribution of graphite and carbides can be controlled by chill effect and alloy content. Adding alloy elements such as manganese, chromium, nickel, and molybdenum can transform the matrix structure from pearlite and bainite to martensite. The presence of a small amount of fine graphite improves the roll’s spalling resistance, thermal cracking resistance, and wear resistance, with minimal hardness drop in the working layer. Suitable for intermediate and finishing stands of bar, wire, and section steel mills.
