The corrosion resistance of mild steel, 13% Cr steel, 18% Cr steel and 18-S Cr-Ni steel against nitric and sulphuric acids mixed has been examined. The corrosion tests are carried out in 98% nitric and 98% sulphuric acids mixed and in 98% nitric and 30% fuming sulphuric acids mixed at 30° and 50°, by measuring the weight loss for 10 hours, and the corrosion rate is expressed as g/m2/hr. The results obtained are shown in Fig. 1_??_12.
