High Chromium Steel Rolls, Enhanced High Chromium Steel Rolls

High chromium steel is similar to high Cr cast iron 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.
