Sulphuric acid test Sulphuric acid immersion stainless steel sheets test can distinguish 302 and 304 from 316 and 317. The cut edge of the sample shall be finely ground and then cleaned and passivated for half an hour in nitric acid (specific gravity 1.42) at a volume concentration of 20~30% and a temperature of 60~66℃. The volume concentration of sulfuric acid test solution is 10%. When heated to 71℃, 302 and 304 steels are immersed in this hot solution, they are rapidly corroded and produce a large number of bubbles, and the sample turns black in a few minutes. In contrast, the 316 and 317 steel samples are not corroded or react slowly (no bubbles are produced), and the samples do not change color within 10 to 15 minutes. More accurate tests can be made if samples with known components are used for approximate comparison.
