321 STAINLESS STEEL PLATE
321 STAINLESS STEEL 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°C where 304 is normally used up to 500°C. Grade 321 has excellent forming and welding characteristics. It does not polish well so would not be used for decorative applications. TW stocks a wide range of sizes in 321 stainless certified to AMS 5510, ASTM A 240, and SA 666.
APPLICATIONS:
- Aircraft exhaust manifolds
- Expansion joints
- Furnace parts
