Grade properties: The matrix structure is pearlite or bainite, respectively. Chromium is a stable element of carbides, molybdenum can improve high-temperature performance, and adding nickel can strengthen the matrix. Half steel rolls have the characteristics of small hardness drop, good wear resistance, good high-temperature performance, and can withstand large loads.
