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.
