The corrosion test of 18% Cr steel was carried out by dip method. The corrosion resistance was examined in 5_??_98% HNO3 at 30_??_70° by measuring the weight loss for 10 hours, and the corrosion rate was expressed as g/m2hr.
The results obtained were as follows (1) At 30°, this steel is not corroded. (2) At 50°, this steel is slightly corroded in conc. nitric acid. (3) At 70°, this steel is slightly corroded in above 50% nitric acid.
