Semi-steel is a commonly used roll material, also known as semi-high-speed steel rolls. It is formed by the combination of the performance characteristics of high-speed tool steel and common alloy structural steel. Semi-steel has high hardness, wear resistance and hot crack resistance, and is suitable for rolling various metal materials, such as iron, steel, aluminum, etc.
