Nickel 200 is often associated with strong resistance to caustic alkalis, but sulfuric acid is a different conversation. Nickel 200 corrosion resistance in sulfuric acid can be useful only under specific reducing, low-oxidizing conditions, and it can deteriorate quickly when oxygen, ferric ions, cupric ions, high temperature, aeration, or high velocity are present. This is why a serious material review never says ‘Nickel 200 is sulfuric-acid resistant’ without naming concentration, temperature, aeration state, and contaminants.<\/p>\n
