Stainless Steel 321 in bars, flanges, pipe fittings and tubes

GRADE STAINLESS STEEL 321, AISI Type 321, UNS S32100

Yaang is a leading manufacturer of Stainless Steel 321 in bars, flanges, pipe fittings and tubes.

Stainless Steel 321 is a stabilized austenitic stainless steel. It is stabilized for weldments subject to sever corrosive conditions and service from 800 to 1600 F. It is similar to stainless steel grade 304 but with a titanium amount of at least five times the level of carbon. This also helps advance the mechanical properties of the steel at higher temperatures.
