Aia ka Ti o 321 stainless steel ma ke ʻano he mea hoʻokūpaʻa, akā he kila ikaika ia, ʻoi aku ka maikaʻi ma mua o 316L.ʻO 321 ke kila kila maikaʻi ke kūpaʻa abrasion i loko o nā waikawa organik a me nā waikawa inorganic o nā ʻano ʻokoʻa a me nā mahana, ʻoi aku hoʻi i ka media oxidizing, i hoʻohana ʻia no ka hana ʻana i nā pahu wai-kūpaʻa a me nā mea paʻa a me nā laina paipu.
ʻO 321 stainless steel ʻo Ni-Cr-Ti austenitic stainless steel, ua like loa kāna hana me 304, akā no ka hoʻohui ʻana o ka titanium metala, no laila ʻoi aku ka maikaʻi o ka palena o ka palaoa a me ka ikaika wela.Ma muli o ka hoʻohui ʻana o ka metala titanium, hoʻomalu pono ia i ka hoʻokumu ʻana o ka chromium carbide.
ʻOi aku ka maikaʻi o ke kila kila 321 kiʻekiʻe kiʻekiʻe.He kūpono ia no nā ʻāpana wili i hoʻohana ʻia i ka wela kiʻekiʻe.
