<p> Multi-component white cast irons containing Cr, Mo, W and V have been widely popularized as roll materials for hot rolling mills because of their excellent wear resistance. In this research, effects of C and Ni contents on mechanical properties and hot wear resistance were investigated using Fe-5%Cr-5%Mo-5%V-5%W-Ni-C (mass%) cast alloys. MC and M2C carbides crystalized in all specimens, and M7C3 carbides appeared in high C and high Ni cast irons. Martensitic matrix was obtained in some specimens with C=1.5mass% and Ni less than 5mass%, and those with 2.0~3.0mass%C and Ni less than 2.5mass%. The addition of 1mass%Ni to cast irons with around 2mass%C improved the hardenability. The increase in Co content led to a transformation of soft pearlite. Martensitic matrix showed over 600HV in micro-hardness, and the variation of macro-hardness was closely related to that of micro-hardness. Tensile strength and compressive 0.2% proof strength were high in cast irons with high hardness. 1.5mass%C-0mass%Ni cast iron showed minimum wear loss or highest wear resistance, and 1.5mass%C-10mass%Ni cast iron showed the largest fracture toughness.</p>
