Product Description

Unit price will be decided by engineering drawing.

Description:
Adding relatively more Chromium alloy elements in its outer layer brings a special carbide structure. Compared with normal roll, it has higher wear resistance, hardness, strength, and campaign rolling tonnage. The core part adopts alloy spheroidal graphite(SGP) to ensure the roll's integral strength.

The combination of the special carbide structure in the outer layer and the high strength SGP core results in a roll with excellent wear resistance, impact resistance, and overall durability.

Moreover, the addition of chromium in the outer layer also improves the roll's resistance to oxidation and corrosion, which is particularly beneficial in industries such as steelmaking and chemical manufacturing where harsh environments can lead to premature roll failure.

Overall, the use of chromium alloy elements in the outer layer and SGP in the core provides a winning combination for roll performance and longevity, making it a preferred choice in heavy-duty roll applications.
