In general, it is resistant to aqueous corrosion because it is made of a nickel-base alloy. In general, stainless steel 304 square bars are resistant to aqueous corrosion because they are made of nickel-based alloys. Stainless steel 304 square bars are an excellent choice for structural applications due to their outstanding resistance to acid and alkali corrosion, stress corrosion cracking, and localised attacks such as pitting and crevice corrosion.
