Metallographic Structure
Metallographic Structure is avaiable to supply.
Unique Features:
* High V, W, Cr, Mo, Nb and other alloy elements.Carbide types: MC and M2C with high hardness and good abrasion resistance.
* Excellent thermal stability, high hardness and good wear resistance.
* High expansion coefficient and good thermal conductivity, more conducive to control
* Forming oxide film during rolling process, improving roll wear resistance significantly
* Super high strength of the roll core (DCI)


Product description
High-performance HSS Roll has high wear resistance and harden ability, especially the red hardness at high temperature, which makes high-performance high-speed steel more suitable for manufacturing rolls and roll rings.
Therefore, high-speed steel rolls are not only suitable for wire and bar mills, but also for plate and strip mills, and have achieved remarkable results.
Superior quality of roll not only to improve the rolling quality, but also help the plant reduce carbon emissions.
