Enhanced High Chromium Iron Roll is widely used in early finishing stands of hot strip mills, skin pass
stands and in finishing stands of small section mills. The high Cr content of the shell material and the absence of free graphite characterize these grades. Different types of carbides with high hardness and a tempered martensitic microstructure guarantee an excellent wear resistance. All high chromium rolls are high temperature heat treated and tempered to obtain optimal properties, Enhanced HiCr rolls are alloyed additionally with W, V and Nb to increase the hardness of eutectic carbides, hence increasing the performance of the rolls significantly, so they will get better performance on these stands.
High chromium steel Roll is similar to high Cr cast iron roll with lower carbon content of 1.0-1.8%.The lower carbon grades are true steel with no eutectic carbides and higher carbon grades have some eutectic carbides.Hi Chromium steel rolls are used in roughing stands of HSMs, Steckle Mills and some early finishing stands of Hot Strip Mills.Enhanced High Chromium Steel Rolls are alloyed with Nb, V and W to improve the wear resistance performance.
