Alloy 321
A Multi-Purpose Austenitic Heat Resistant Stainless Steel with Oxidation Resistance Under Mildly Cyclic Conditions to 2010°F (1100°C)

Alloy 321 (UNS S32100) is an austenitic stainless steel developed for use in high temperature corrosion resistant applications. The alloy resists oxidation up to 2010oF (1100oC) under mildly cyclic conditions.

Because of its high chromium and moderate nickel content, Alloy 321 is resistant to sulfidation and can also be used in moderately carburizing atmospheres.

321S (UNS S32108) is the low carbon version of the alloy. It is utilized for ease of fabrication. 321H (UNS S32109) is a high carbon modification developed for enhanced creep resistance. In most instances the grain size and carbon content of the plate can meet both the 321S and 321H requirements.

Alloy 321 can be easily welded and processed by standard shop fabrication practices.

Fabrication Data
Alloy 321 can be easily welded and processed by standard shop fabrication practices.

Hot forming
Heat uniformly at 1742 – 2192°F (950 – 1200°C). After hot forming a final anneal at 1832 – 2101°F (1000 – 1150°C) followed by rapid quenching is recommended.

Cold forming
The alloy is quite ductile and forms in a manner very similar to 321. Cold forming of pieces with long-term exposure to high temperatures is not recommended since the alloy is subject to carbide precipitation and sigma phase precipitants.

Welding Alloy 321 can be readily welded by most standard processes including TIG, PLASMA, MIG, SMAW, SAW and FCAW.
