FERRITIC STAINLESS STEEL WITH IMPROVED SURFACE QUALITY

摘要

A ferritic stainless steel with improved surface quality is disclosed. The disclosed ferritic stainless steel is by weight %, C: 0.02% or less (excluding 0), Si: 0.3 to 0.6%, Mn: 0.2 to 0.6%, Ti: 0.15 to 0.3%, Cr: 17 to 26%, Ni : 0.6% or less (excluding 0), Nb: 0.35 to 0.6%, N: 0.05% or less (excluding 0), the remainder contains Fe and inevitable impurities, and satisfies the following formula (1) . Equation (1): 2.7 ≤ (Mn+Si)/Ti ≤ 7.5 (Here, Mn, Si, and Ti mean weight% of each element.)
