Alloy Cast Steel Rolls
What are Alloy Cast Steel Rolls?
Alloy cast steel rolls are essential in modern rolling mills, offering high strength, toughness, and excellent wear resistance. Produced with alloyed steel and elements such as chromium, nickel, and molybdenum, these rolls deliver superior thermal stability and long service life.
Key Benefits
- Exceptional load-bearing capacity
- Extended wear resistance for reduced downtime
- Reliable thermal fatigue resistance
- Versatility for hot strip mills, plate mills, and section mills
