FERRITIC STAINLESS STEEL WITH IMPROVED SURFACE QUALITY

摘要

Disclosed is ferritic stainless steel with improved surface quality. The disclosed ferritic stainless steel contains, by wt%: 0.02% or less of C (0 is exclusive); 0.3-0.6% of Si; 0.2-0.6% of Mn; 0.15-0.3% of Ti; 17-26% of Cr; 0.6% or less of Ni (0 is exclusive); 0.35-0.6% of Nb; 0.05% or less of N (0 is exclusive); and the remainder consisting of Fe and inevitable impurities, and satisfies the following equation (1), equation (1): 2.7 = (Mn+Si)/Ti = 7.5, where Mn, Si, and Ti mean wt% of each element.
