321 ke titanium e tsitsitseng chromium-nickel austenitic stainless steel e nang le matla a matle le ho hanyetsa ha kutu, joalo ka ha e fanoa ka mokhoa o tloaelehileng oa brinell hardness ea 175. lijo tse akaretsang, litharollo tse bolaeang likokoana-hloko, li-dyestuffs, boholo ba lik'hemik'hale tse phelang hammoho le mefuta e mengata e fapaneng ea lik'hemik'hale tse sa tloaelehang, le likhase tse chesang tsa petroleum, likhase tse tukang ka mouoane, asiti ea nitric, le ho isa tekanyong e nyane sulfuric acid.E bonts'a khanyetso e ntle ea oxidation mochesong o phahameng e na le khanyetso e ntle ho kutu ea intergranular mme e na le ts'ebetso e ntle haholo ea ho cheseha.321 e ke ke ea thatafatsoa ke kalafo ea mocheso, empa matla le boima li ka eketsoa haholo ka ho sebetsa ka mokhoa o batang, 'me ka mor'a moo ho fokotseha ha ductility.
E sebelisoa haholo bakeng sa lits'ebetso moo tlatsetso ea titanium le phello ea eona ea ho tsitsisa e le ntho e etsang carbide e lumellang hore e chesetsoe le / kapa e sebelisoe ka har'a sebaka sa pula ea carbide 430.oC - 870oC ntle le kotsi ea ho bola ha intergranular.Tsena li kenyelletsa Phetoho ea Lijo, Lisebelisoa tsa lebese, Lik'hemik'hale, Petrochemical, Lipalangoang le liindasteri tse amanang le tsona joalo-joalo.
Sesebediswa se senang makenete se maemong a mabe, empa se ka fetoha makenete hanyane kamora ho sebetsa ha serame se matla.
Ho lokisoa hoa hlokahala ho lokisoa ha ho hlokahala.
NB Optimum corrosion resistance e fihlellwa maemong a annealed.
