Buttweld Stainless Steel 304 Fittings are widely used in corrosive applications due to their excellent corrosion resistance when exposed to various corrosive environments. It is highly susceptible to pitting and crevice corrosion as a result of chlorides in the environment. At high temperatures, these fittings are resistant to stress corrosion cracking. Buttweld Stainless Steel 304L Because of their resistance to carbide precipitation, fittings are recommended for corrosion resistance in the water.
SS 304 is austenitic steel that contains 18% chromium, 8-10% nickel, 0.07 percent carbon, and other elements. Carbon value is reduced by 0.03 percent in SS 304L. Stainless steel 304 and 304L have chemical and mechanical properties that are similar. Because stainless steel 304 is so versatile, it is widely used.
