SS 321 alloy is a chromium-nickel steel grade. SS 321 welded pipes have high corrosion resistance to atmospheric conditions, sterilizing solutions, various organic chemicals, as well as a variety of inorganic chemicals. Stainless Steel 321 Welded Pipes is a common austenitic 18/8 stainless steel alloy. The titanium content makes it a good option for high pressure environments of up to 900 degrees Celsius.

We are involved in the production of 321-grade pipes and tubes of different types across India. They are, SS 321 Welded pipes/ tubes, SS 321 ERW Pipes/Tubes, and SS 321 EFW pipes/tubes.Stainless Steel 321H is a high carbon version of the 321 grade which offers a higher temperature strength. The Stainless Steel 321 Welded Pipes and SS 321 Welded Tubes display very good welding and forming capabilities. Owing to this functionality, these pipes and tubes are widely used in temperatures ranging from greater than 500 degrees C.

Our SS 321 EFW pipes are mainly applicable in manufacturing of pressure vessels, heat exchangers, pharmaceutical equipment and chemical processing equipment in Gujarat, India.
