HIGH CHROMIUM STEEL ROLLS
The hardness of HiCrS rolls is as high as 60-85HSC. Its matrix gives itself excellent wear resistance and good fire-crack resistance. HiCrS rolls have a low carbon content range of about 10%. An important feature of HiCrS is that the mill is not required to adjust special water cooling conditions. In the rolling process these rolls can form oxide film to improve surface quality of the rolled material. These rolls are suitable for both 2-Hi roughing and front stand of 4 Hi finishing for hot strip mills.
