PROBLEM TO BE SOLVED: To provide a heat-resistant ferritic stainless steel sheet with high weldability.SOLUTION: A heat-resistant ferritic stainless steel sheet with high weldability includes, by mass, C: 0.02% or less, N: 0.02% or less, Si: 2% or less, Mn: 2% or less, P: 0.005-0.025% and P[%]≤-0.05×Nb[%]+0.04, S: less than 0.002%, Cr: 10-20%, Cu: 0.4-3%, Nb: 0.05-0.6%, Ti: 0.005-0.25%, Al: 0.2% or less, B: 0.0001-0.0030%, with the balance being Fe and inevitable impurities. The heat-resistant ferritic stainless steel sheet may also contain one or more of Mo: 0.01-1%, W: 1% or less, V: 1% or less, Co: 1% or less, Ni: 0.5% or less, Zr: 1% or less, and Sn: 0.3% or less. |
