FERRITIC STAINLESS STEEL HAVING SUPERIOR PITTING CORROSION RESISTANCE

摘要

PURPOSE:To improve the pitting corrosion resistance and machinability by adding prescribed percentages of C, Si, Cr, Mn and S to Fe. CONSTITUTION:The titled ferritic stainless steel consists of, by weight, =0.08% C, =2% Si, 11-25% Cr and the balance Fe and satisfies an equation Mn%X S% =0.005. The steel has superior pitting corrosion resistance and machinability, and a high degree of desulfurization is made unnecessary by regulating the composition.
