Alloy 321 (UNS S32100) ke titanium e tsitsitseng kapastenitic stabilized steel stabilized e nang le khanyetso e ntle ea kutu. E na le khanyetso e babatsehang ea ho bola ha intergranular ka mor'a ho pepesehela mocheso sebakeng sa chromium carbide sa 800 - 1500 ° F (427 - 816 ° C). Alloy e hanela oxidation ho 1500 ° F (816 ° C) 'me e na le thepa e phahameng ea ho phunyeha le khatello ea maikutlo ho feta li-alloys 304 le 304L. E boetse e na le boemo bo botle ba mocheso o tlase.
Alloy 321H (UNS S 32109) ke mofuta o phahameng oa carbon (0.04 - 0.10) oa motsoako. E ile ea ntlafatsoa bakeng sa khanyetso e matlafalitsoeng ea li-creep le matla a holimo mochesong o ka holimo ho 1000oF (537°C). Maemong a mangata, likahare tsa carbon tsa poleiti li etsa hore ho be le setifikeiti se habeli.
Alloy 321 e ke ke ea thatafatsoa ke phekolo ea mocheso, feela ka ho sebetsa ho batang. E ka tšeloa habonolo le ho sebetsoa ka mekhoa e tloaelehileng ea ho etsa mabenkele.
