321 Stainless Steel Pipe

321 stainless steel pipe is a high-strength, high-temperature resistant and corrosion-resistant stainless steel pipe, commonly used for pipeline transportation under high temperature and high pressure environments.

 

It contains titanium in its composition, which can improve the pipe's antioxidant and corrosion resistance.

🔵 Description:

 

 

321 stainless steel is an 18/8 austenitic stainless steel (304) stabilized with titanium. This grade will not suffer from intergranular corrosion after heating in the carbide precipitation temperature range of 425-850°C. 321 is used in applications up to about 900°C, combining high strength, phase stability for oxidation resistance and subsequent aqueous solution corrosion resistance.
