HSS ROLLS

High-carbon high-speed steel roll (HSS roll) is the hot-roll material with the shortest appearance, the fastest development, and the widest application prospect. High-speed steel, also known as wind steel or front steel, means that it hardens even when cooled in the air when quenched and is sharp. It is complex alloy steel with carbide-forming elements such as tungsten, molybdenum, chromium, and vanadium. The total amount of alloy elements reaches about 10%~25%.

The application of high-speed steel rolls is an important part of the development of modern steel rolling production. It is another significant change to the development of the iron and steel industry after micro alloying, controlled rolling, and controlled cooling technology.

The good wear resistance of high-speed steel rolls is inseparable from the obvious difference from traditional rolls. High-speed steel rolls contain a large amount of alloying elements such as W, Mo, Cr, V, and Co. The hardness, thermal crack resistance, and thermal shock resistance of high-speed steel rolls are superior to cast iron rolls, and their wear resistance is 3-5 times that of cast iron rolls.
