We manufacture this type of rolls by adding Mn, Cr, Ni, Mo and other alloy elements, with present of minute graphite, the roll can be ensured being raised the properties of resistance to spalling , firecrack and wear as well as maintaining the surface hardness almost no drop. The bitting ability is also be improved owing to the existance of minute graphite porosities.

This type of rolls is suitable for intermediate rolling of normal mills and Intermediate and finishing stands of section mills.
