<p><P>PROBLEM TO BE SOLVED: To provide a heat resistant ferritic stainless steel sheet having excellent oxidation resistance. <P>SOLUTION: The heat resistant ferritic stainless steel sheet having excellent oxidation resistance includes a composition comprising, by mass%,≤0.008% C,≤0.02% N, 0.1 to 0.5% Si, 0.5 to 1.5% Mn, 14 to 19% Cr, 0.8 to 2% Cu,≤0.2% Ni, 0.2 to 0.8% Nb and 0.01 to 0.3% Ti, and the respective elements are regulated each other so that formula (1) is≤0, and the residue comprises Fe and inevitable impurities. The steel sheet may comprise 0.02 to 0.5% V, 1 to 2% Mo, 0.0002 to 0.0050% B,≤3% Al,≤3% W and≤1% Sn:γp=420×[%C*]+470×[%N*]+23×[%Ni]+9×[%Cu]+7×[%Mn]-11.5×[%Cr]-11.5×[%Si]-52×[%Al]-12×[%Mo]-47×[%Nb*]-23×[%V]+189 (1). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
