Abstract
A roll material comprising, in proportions by weight, 0.04-0.20% C, 0.2-0.8% Si, 0.4-1.5% Mn, 0.2-1.0% Ni, 10.0-14.0% Cr, 0.5-4% Cu, 0.1-0.5% V, 0.01-0.35% Nb, 0.01-0.06% Al, P and S each in a reduced amount of up to 0.03% as impurity elements, and the balance Fe. The material is comparable in resistance to high-temperature oxidation in 13Cr martensitic stainless steels which are presently used and yet has outstanding strength at high temperatures.
