Stainless Steel, Austenitic

321 Stainless Steel (S32100) Coil

A titanium-stabilised chromium-nickel austenitic stainless steel with very good corrosion resistance.

Stainless steel 321 is the stabilized version of stainless steel 304. The 18/8 blend of chromium and nickel is tempered with titanium to give type 321 protection from intergranular corrosion that can occur after heat treatment. It is protected from temperatures ranging from 800 to 1500° F. The metal displays high strength and resistance to various forms of corrosions, including that from aqueous environments.

Type 321 finds application in heavy welding components, along with dynamic environments that are subject to changes.

However, the addition of titanium limits the application of 321 in terms of working. The metal is not recommended for certain welding techniques as it is not consumable. Beyond this, stainless steel 321 has excellent forming characteristics, does not require annealing after being welded, and displays toughness in a range of temperatures.

The metal shows strength even when exposed to cryogenic temperatures. Additionally, it is often chosen over Type 304 for its increased resistance to creep and rupture. Both metals may be susceptible to stress corrosion cracking.
