Product Description Product DescriptionBrief Introduction of HSS RollHigh-speed steel (HSS) rolls are advanced metallurgical products widely used in the modern steel industry for hot rolling applications. These rolls are known for their exceptional wear resistance, high-temperature hardness, and thermal fatigue resistance. Composed of alloy elements such as tungsten (W), molybdenum (Mo), vanadium (V), and chromium (Cr), HSS rolls exhibit superior durability and performance compared to traditional cast iron and cast steel rolls. By adopting high-speed steel rolls, steel manufacturers can achieve improved efficiency, lower maintenance costs, and superior product quality.
