A new steel with high Cr and low W, Mo contents for forged cold work roll was designed based on the composition system of traditional high-speed steel roll. The Fe-C isopleths of the steel and the mass fraction of equilibrium phases versus temperature were calculated by Thermo-Calc, and the effects of different alloying elements (W, Mo, Cr, V) on austenite, ferrite, and carbides (MC, .
