China Hexagon Round Square Hollow ASTM A276 UNS S32100 DIN 1.4541
321 Bar
1. 321 Round Bar Stainless Steel Round Bar T-321 contains increased
titanium for improved strength and heat resistance, making it ideal
for applications in temperatures up to 900°C. Stainless 321 round
bar is a choice material in applications involving welding or
sustained elevated temperature operations where re-annealing is not
practical.
Properties: hardenable by cold working, high strength, high
resistance to corrosion, excellent resistance to intergranular
corrosion, readily formed and drawn, and non-magnetic.
Common Uses: used extensively in the aircraft and missile
industries for engine parts, heat exchangers, exhaust stacks,
rocket engines, and manifolds.

Description:
Type 321 is an austenitic chromium-nickel stainless steel
containing Titanium which is recommended for parts fabricated by
welding which cannot subsequently be annealed.Type 321 is a
stabilized austenitic stainless steel similar to type 304 but with
a titanium addition.
