Stainless Steel 321/321H Seamless Pipes Manufacturers, Suppliers, Stockists, and Exporters. Characterized by its heat resistance and titanium stabilization, Alloy 321, or UNS S32100, has carved its niche for applications demanding consistent service within the 1000°-1600°F temperature spectrum. Known under the designation WNR 1.4541, our SS 321 Seamless Pipes bear striking similarities to Grade 304, yet boast a unique titanium addition, exceeding its carbon content by fivefold. Dive into our collection, and you'll find that our Stainless Steel 321 Welded Tubes can be tailored to bespoke lengths and configurations, all while ensuring affordability.

While both variants are part of the stainless steel family, their carbon content delineates them significantly. The elevated carbon composition in 321 stainless steel amplifies its yield strength. This characteristic makes 321 stainless steel an ideal choice for high-temperature settings, outperforming the 304 alloy in terms of ductility and resistance against stress fractures.
AISI 316 steel reigns supreme when it comes to battling extreme corrosive environments, making it a go-to choice for acid-resistant applications. On the other hand, the AISI 321 variant, championed by Kamal Piping, boasts exceptional resistance against intracrystalline corrosion. Moreover, its resilience shines through when operating in elevated temperatures, specifically ranging between 400–800°C.
