I test corrosion resistance of steels by heat treating 1 x 1.5 inch coupons, finishing to about 400 grit, and then spraying with water. A mirror finish is the best at resisting corrosion and a rough finish means rust and corrosion is more likely. Distilled water can separate steels that are stainless vs those that are not.
