<P>PROBLEM TO BE SOLVED: To provide a ferrite stainless steel sheet having high oxidation resistance and excellent resistance to scale peeling even at high temperature around 1,000°C. <P>SOLUTION: The ferrite stainless steel sheet having excellent oxidation resistance, contains ≤0.020% C, ≤0.020% N, >0.10 to 0.35% Si, 0.10-0.60% Mn, 16.5-20.0% Cr, 0.30-0.80% Nb, >2.50 to 3.50% Mo, 1.00-2.50% Cu, and exhibits an oxidation mass increase of ≤4.0 mg/cm<SP POS="POST">2</SP>after an atmospheric continuous oxidation test of 200 hours at 1,000°C, and exhibits a scale-peeling amount of ≤1.0 mg/cm<SP POS="POST">2</SP>. To the steel sheet, one or more kinds of ≤2.0% W, ≤0.20% Ti, ≤0.0030% B, ≤0.0100% Mg, ≤1.0% Al, ≤1.0% Ni, ≤1.00% Sn, ≤0.50% V, ≤1.0% Zr, ≤1.0% Hf and ≤3.0% Ta, can be added. <P>COPYRIGHT: (C)2012,JPO&INPIT |
