Hss High Strenght Rust Proof Enhanced High Speed Steel Roll

a High-speed steel rolls have good thermal stability, and the roll surface has high hardness and good wear resistance at rolling temperature.
a The high-speed steel roll has good hardenability, and the hardness hardly decreases from the surface of the roll body to the inside of the working layer, thus ensuring that the roll has the same good wear resistance from the outside to the inside.
a During the use of the high-speed steel roll, under good cooling conditions, a thin and dense oxide film is formed on the surface of the roll body. This uniform, thin and dense oxide film can exist for a long time without falling off, making the high-speed steel roll wear-resistant.
