Multi-component white cast irons containing Cr, Mo, W and V are widely popular as roll materials for hot strip finishing mills because of their excellent wear resistance. Work rolls of multiple rolling mills applied usually to hot strip finish rolling are required to endure the contact pressure generated by rolling force between work roll and back-up roll or intermediate roll. In this research, effects of alloy and C contents on compressive properties were investigated. 0.2% compressive proof strength was found to increase with increase in hardness. It was also found that the relation is σ0.2 (MPa)=3.52・HV30-588 for irons with martensitic and fine pearlitic matrices. The equation Pmax=1.65・σ0.2% was obtained between Hertzian contact pressure and compressive proof strength. In order for rolls to endure contact pressure of 2.6GPa, compressive proof strength over 1.6GPa is necessary and multi-component white cast irons with macro-hardness over 600HV30 can be said to be appropriate roll materials for recent hot strip finishing mills applied by heavy load.
