Belonging to hyper-eutectoid steel, whose worklayer contains a certain amount of carbide, body hardness is very high. Hardness drops little from the surface to the center. When the roll use in the section mill, it has good wear resistance, tensile strength and can meet the requirement. The heat treatment enables matrix organizations granular pearlite. The strength and toughness are improved.
