Stainless Steel 321 welded pipes have high corrosion resistance to atmospheric conditions, sterilizing solutions, various organic chemicals, as well as a wide range 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-temperature conditions of up to 900 degree C.

Preston Pipes and Alloys is highly active in the production 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. SS 321H is a higher carbon version of the 321 grade providing a higher temperature strength. These Stainless Steel 321 Welded Pipes and Stainless Steel 321 Welded Tubes show good welding and forming abilities. Owing to this functionality, these pipes and tubes are widely used in temperatures ranging from more than 500 degrees C.

Our Stainless Steel 321 EFW pipes are majorly applicable in manufacturing of pressure vessels, heat exchangers, pharmaceutical and chemical processing equipment in Gujarat, India. We fabricate these 321 grades ERW pipes and tubes in different sizes, dimensions, thicknesses, and lengths in Mumbai, India. Apart from the standard sizes, we also manufacture our pipes and tubes in custom sizes according to our esteemed customer’s demand in Rajasthan, India.

The Stainless Steel Welded 321H Tubes are generally used in applications that require heating temperature between 800 degrees F and 1650 degree F, for example, aircraft collector rings, exhaust manifolds, expansion joints, and high-temperature chemical process equipment.
