Stainless Steel 321 Rectangle Tubing

321 stainless steel rectangle tubing comprises mainly iron, 18% chromium, and 9% nickel. It also contains traces of manganese, silicon, and titanium. The nickel component gives this material superior toughness and ductility over other stainless steel alloys due to its ability to resist cyclic stress crack corrosion. It also has excellent creep strength and good formability in both annealed and cold-worked conditions, with high resistance to scaling at elevated temperatures.

Stainless Steel 321 rectangle tubing is used in various applications, including exhaust systems, heat exchangers, power generation components, and pressure vessels. It is also well-suited for use in cryogenic and high-temperature environments. 321 stainless steel rectangle tubing properties include excellent corrosion resistance to oxidation at high temperatures, good strength, and toughness, weldability, formability, and machinability. It also offers excellent stress corrosion cracking resistance and superior creep strength compared to other grades of stainless steel alloys.
