Product Description

A312 Tp321 Seamless Stainless Steel Tubing

Stainless steel 321 grade is an austenitic grade of steel product. The Stainless Steel 321 Pipe is designed with a superior chemical composition consisting of chromium and nickel while being stabilized by titanium. These pipes showcase superior strength and can be utilized in an array of corrosive and reducing media. The 321 Stainless Steel Pipe can be used in temperatures between 538 to 870 degrees C. They have a minimum tensile strength of 515mpa with a minimum yield strength of 205mpa. The pipes in the SS 321 grade can be easily elongated by 40% and possess a hardness of Rockwell 95 HRB max. This versatile grade of pipes possesses an excellent forming capacity and can be welded in place following standard welding procedures.
The robust 321 Stainless Steel Tubing can be either hot or cold rolled and further heat treated. These tubes are generally annealed at temperatures around 1605 degrees F, followed by a water quenching process. This gives the tubing enhanced resistance to corrosive media.
