Stainless Steel Comparison

302
AISI 302 is the most basic type of steel in the chromium-nickel group. It is an austenitic steel, which is used for chemical resistance and hardenable by cold work. It contains 18% chromium and 8% nickel. It has corrosion resistance to mild-atmospheric and fresh water, industrial atmospheric, marine atmospheric, mild chemical and oxidizing chemical environments. Type 302 is also highly resistant to gasoline.

303
AISI 303 is an austenitic steel in the chromium-nickel group, which is hardenable by cold work and used for chemical resistance. It has added silicon for easier machinability. It has corrosion resistance to mild-atmospheric and fresh water, industrial atmospheric, and mild chemical environments. Type 303 is not resistant to gasoline, unlike basic type 302 steel.

304
AISI 304 is an austenitic steel in the chromium-nickel group, which is hardenable by cold work and used for chemical resistance. It contains lower carbon in order to avoid carbide precipitation. It has corrosion resistance to the same environments as type 302, including gasoline.

316
AISI 316 is an austenitic steel in the chromium-nickel group, which is hardenable by cold work and used for chemical resistance. It contains added molybdenum for increased corrosion resistance. At room temperature type 316 displays low corrosion rates to low and high concentrations of sulfuric acid as opposed to the basic type 302, which is not mentioned to have resistance to sulfuric acid. Type 316 also has notable corrosion resistance to chlorides, nitric acid, acetic acid and gasoline. It has corrosion resistance to every notable environment, including all atmospheric and chemical situations. Resistance to saltwater corrosion and reducing chemical environments are unique properties of type 316.
