Will SUS 444 stainless steel rust after being corroded by nitric acid, heated and dried, and left at room temperature?
It's hard to say. First of all, the main advantage of SUS444 stainless steel is chloride ion corrosion resistance, not nitric acid, which is also related to the concentration of nitric acid. Sweat chloride ion solution is generally used in experiments, and the chloride ion corrosion resistance of SUS444 is better than that of 304. So it is not easy to answer the experiment with nitric acid.
