321 stainless steel (1.4541) has excellent corrosion resistance at normal temperatures but is primarily designed to perform at elevated temperatures.

Corrosion Resistance

321 stainless steel (1.4541) has excellent corrosion resistance at normal temperatures but is primarily designed to perform at elevated temperatures. The added titanium content of minimum five times the carbon % content (max 0.7%) means that grade 321 also possesses good creep strength, good resistance to chromium carbide precipitation and is very resistant to oxidation and intergranular corrosion up to 850ºC in dry air service conditions. Other corrosive compounds in the hot atmosphere such as water and sulphur compounds will significantly reduce the maximum service temperature. The overall characteristics of this material make it an excellent, relatively low cost choice for many applications.
