FERRITIC STAINLESS STEEL SHEET |
| 摘要 |
To provide a ferritic stainless steel sheet which has high scale spalling even at a high temperature around 1000° C. Provided is a ferritic stainless steel sheet having excellent Mn-containing oxide film-forming ability and scale spalling ability, containing, in terms of mass %: C: 0.001 to 0.020%, N: 0.001 to 0.020%, Si: 0.10 to 0.40%, Mn: 0.20 to 1.00%, Cr: 16.0 to 20.0%, Nb: 0.30 to 0.80%, Mo: 1.80 to 2.40%, W: 0.05 to 1.40%, Cu: 1.00 to 2.50%, and B: 0.0003 to 0.0030%, in which the above-mentioned components are contained satisfying the formula (1) below, and the balance is composed of Fe and inevitable impurities. At least one of N, Al, V, Mg, Sn, Co, Zr, Hf, and Ta may be added in a predetermined content range.;3≦(5×Mo)/(3×Mn)≦20 (1) |
