Stainless Steel 321 alloy is a chromium-nickel steel grade. Stainless Steel 321 welded pipes are resistant to atmospheric corrosion, sterilizing solutions, various organic chemicals, and a wide range of inorganic chemicals. Stainless Steel 321 Welded Pipes is a common austenitic 18/8 stainless steel alloy. The addition of titanium makes it a good option for high-temperature conditions below 900 degree C.

Preston Pipes and Alloys is highly active in the manufacturing of 321-grade pipes and tubes of different types across India. They include, 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 offering a higher temperature resistance. These SS 321 Welded Pipes and SS 321 Welded Tubes show good welding and forming abilities. Owing to this functionality, these pipes and tubes are widely used in temperatures ranging from greater than 500 degrees C.

The SS 321H pipes are mainly used in manufacturing of pressure vessels, heat exchangers, pharmaceutical equipment and chemical processing equipment in Gujarat, India.
