What are the Stainless Steel 321 Pipes?

Austenitic stainless steel with a settled structure and improved overall corrosion resistance is known as stainless steel 321 pipes. After exposure to temperatures in the chromium carbide precipitation range of 800-1500 degrees F (427-816 degrees C), it exhibits incredible resistance to intergranular corrosion. The stainless offers stronger creep and stress rupture qualities than SS 304 and 304L and maintains oxidation up to 1500 degrees F (816 degrees C). Furthermore, it keeps its good low-temperature durability.

The Stainless Steel 321 Pipes is the version of SS 321 with a greater carbon content (0.04-0.10). It was created to increase strength at temperatures above 1000 degrees Fahrenheit and improve creep resistance (537 degrees C). The carbon content of the plate typically allows for dual certification. These Stainless 321 can only be cold worked; heat treatment cannot be used to harden them. It can be successfully welded and treated using common fabrication shop techniques.

Applications of Stainless Steel 321 Pipes

Similar to 304, stainless steel 321 pipes exhibit good all-around corrosion resistance. It was developed for usage in the 1800–1500 °F (416–816 °C) chromium carbide precipitation range, where unstabilized alloys, such as 304, are vulnerable to intergranular assault. The alloy can be used in pure phosphoric acid at low temperatures, the majority of diluted organic acids at moderate temperatures, and up to 10% diluted solutions at high temperatures. In hydrocarbon service, polythionic acid stress corrosion cracking is resisted by SS 321 pipes. At mild temperatures, it can also be utilized in fluoride- or chloride-free caustic solutions. Even at low concentrations, stainless steel 321 does not function well in sulfuric acid service or chloride solutions.
