抄録

17%Cr-7%Ni stainless steel containing 0.93%Al was used for the experiments of acid corrosion resistance after several heat treatments such as solution treatment at 1050°, cooling from 750∼800°C in water or air and aging at 400∼500°C for 0.5∼500 hr. As corrosion reagents, 10 wt% sulphuric acid (30°C) and 40 wt% nitric acid (boiling) solutions were used. The following results were obtained; (1) Against 10 wt% sulphuric acid solution, this steel aged at a lower temperature than that for obtaining max. mechanical properties showed as strong corrosion resistivity as 18-8 stainless steel. Specimens heat-treated under such desirable condition attained a passive state in the soaking time up to 12 hr. (2) Against 40 wt% boiling nitric acid solution, this steel heat-treated under suitable conditions shows corrosion resistivity superior to that of 18-8 stainless steel.
