PURPOSE:To improve the toughness without reducing the effect of inhibiting intergranular corrosion by reducing the amounts of C and N contained in a martensite phase in a supersatd. state. CONSTITUTION:The composition of a ferritic stainless steel is composed of, by weight, <0.03% C, <0.02% N (C+N<0.04%), 11-20% Cr, <3.5% Mn, <2% Mi, <1% Si and the balance Fe with inevitable impurities, and the chemical components are regulated so as to satisfy 40-110 austenite potential Pa calculated by the equation.
