Stainless Steel 321 Plate

321 stainless steel plates are part of the austenitic family of stainless steel. 321 is basically a 304 grade containing a stabilizer of titanium. Type 321 is a good choice for applications where heat is an issue. 321 can be used in applications up to 900 degrees Celsius where 304 is normally used up to 500 degrees Celsius. Grade 321 has excellent forming and welding characteristics. It does not polish well so would not be used for decorative applications. Aakash Steel stocks a wide range of sizes in 321 stainless certified to AMS 5510, ASTM A 240, and SA 666

Alloy 321 (UNS S32100) is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 – 1500°F (427 – 816°C). The alloy resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L. It also possesses good low temperature toughness.
