Alpha Overseas manufactures and trades SS 321 Butt Weld Pipe Fittings, which are the basic austenitic 18/8 steel stabilised by Titanium or Niobium additions. These Alloy 321 Elbow Butt Weld Pipe Fittings is similar to Type 304 stainless steel; however, it contains a Titanium addition of at least five times the carbon content. Our Grade 321 Tee Butt Weld Pipe Fittings is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 Degree C to 1500 Degree F (427 Degree C to 816 Degree C). These Type 321 Reducer Butt Weld Pipe Fittings is titanium stabilised chromium-nickel austenitic stainless steel with good strength and excellent corrosion resistance, as supplied in the annealed condition with a typical brinell hardness. Comparing the chemical composition of our AISI 321 Cross Butt Weld Pipe Fittings and SS 304 / 304L, it is clear that the chromium (Cr) and nickel (Ni) ranges of these alloys are very similar.
