<p><P>PROBLEM TO BE SOLVED: To provide a ferritic single phase stainless steel slab which prevents the generation of cracks even when it is cooled to ordinary temperature. <P>SOLUTION: The ferritic single phase stainless steel slab has a composition containing, by mass,≤0.020% C,≤2.0% Si,≤2.0% Mn,≤0.050% P,≤1.2% Ni, 11.0 to 25.0% Cr, 0 (including no addition) to 1.0% Mo,≤0.020% N,≤0.25% Ti, and≤0.10% Al, and the balance Fe with inevitable impurities. Further, the precipitated P content precipitated as FeTiP is less than 0.007%. The ferritic single phase stainless steel slab is produced by subjecting a molten steel having the above componential composition to continuous casting into a slab, and this slab is water-cooled in order to keep recuperation maximum temperature below 670°C, and then air cooled down to an ordinary temperate. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
