Hot Working Die Steel Rolls

The hot work die steel roll has high thermal strength, high thermal stability, good wear resistance, cold and thermal fatigue resistance, and tempering stability. It is applicable to the cogging roll, rough roll, and backup roll of large-section steel.

Hot work die steel rolls are rolls specially designed to work in high-temperature environments. They are usually used in hot rolling processes, such as hot rolling of steel, hot rolling of non-ferrous metals, etc. Hot work die steel rolls can maintain high strength and hardness at high temperatures to withstand high loads during rolling. They have good thermal stability and can maintain their performance even under long-term high-temperature working conditions. They can resist thermal fatigue caused by temperature changes and reduce the risk of cracks and fractures. Hot work die steel usually contains alloying elements such as chromium, molybdenum, vanadium, etc., which improve the wear resistance of the rolls. Although the initial cost of hot work die steel rolls may be higher, their long life and low maintenance requirements can reduce maintenance costs in the long run. Hot work die steel rolls are able to work in harsh industrial environments, including high temperature, high pressure, and chemical corrosion environments.
