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. Company Profile
