Ingxubevange 321 (UNS S32100) yi titanium uzinzile austenitic intsimbi engatyiwa kunye elungileyo ukumelana umhlwa jikelele. Inokumelana okugqwesileyo kwi-intergranular corrosion emva kokuvezwa kumaqondo obushushu kuluhlu lwemvula ye-chromium carbide ye-800 - 1500 ° F (427 - 816 ° C). I-alloy iyamelana ne-oxidation ukuya kwi-1500 ° F (816 ° C) kwaye ineempawu eziphezulu zokunyuka kunye noxinzelelo lwexinzelelo kune-alloys 304 kunye ne-304L. Ikwanayo nokuqina okuhle kobushushu obuphantsi.
I-alloy 321H (UNS S 32109) yi-carbon ephezulu (0.04 - 0.10) version ye-alloy. Yaphuhliselwa ukomelezwa kokuxhathisa kokurhubuluza kunye nokomelela okuphezulu kumaqondo obushushu angaphezu kwe-1000oF (537°C). Kwiimeko ezininzi, umxholo wekhabhoni weplate uvumela ukuqinisekiswa kabini.
I-alloy 321 ayikwazi ukuqina ngonyango lobushushu, kuphela ngokusebenza okubandayo. Inokuthi idityaniswe ngokulula kwaye iqhutywe ngeendlela eziqhelekileyo zokwenziwa kweevenkile.
