321 Stainless Round Bar Stock

321 Stainless has excellent corrosion resistance properties.

321 Stainless

321 Stainless is an excellent choice for high-temperature applications due to its average austenitic composition.

It is a typical austenitic 18/8 chromium-nickel alloy with titanium added. Moreover, because it has been subjected to high temperatures, it has developed a high level of resistance to intergranular corrosion. Intergranular corrosion is less likely to occur because of the titanium’s strengthening effect on the material. That is why 321 is chosen as the stainless steel of choice for applications that require up to 900° C.

Machinability & Welding

Cold working is the only method of hardening 321 stainless. Heat treatment is not an option. It is easily welded using any standard procedure, and it does not require any post-weld annealing after the welding process. 321 Stainless is ductile, which means it can be formed with relative ease. When used in chloride solutions, 321 has excellent corrosion resistance, especially against dilute organic acids; however, it is susceptible to pitting and crevice corrosion, making it unsuitable for these applications.

Applications

Chemical Processing, polythionic acid service, and thermal oxidizers are some of the many applications of 321 Stainless.
