Alloy 321 (UNS S32100) ititanium yakagadzikana austenitic Stainless simbi ine yakanaka general corrosion resistance. Iyo ine yakanakisa kuramba kune intergranular corrosion mushure mekusangana kune tembiricha muchromium carbide kunaya kwe800 - 1500 ° F (427 - 816 ° C). Iyo alloy inoramba oxidation kusvika 1500 ° F (816 ° C) uye ine yakakwirira inokambaira uye kusagadzikana kuputika zvivakwa kupfuura alloys 304 uye 304L. Iyo zvakare ine yakanaka yakaderera tembiricha kuoma.
Alloy 321H (UNS S 32109) ndiyo yakakwira kabhoni (0.04 - 0.10) shanduro yealloy. Yakagadzirirwa kukwidziridzwa kuramba uye simba repamusoro pane tembiricha iri pamusoro pe1000oF (537°C). Muzviitiko zvakawanda, iyo kabhoni yemukati yeplate inogonesa mbiri mbiri.
Alloy 321 haigoni kuomeswa nekurapa kwekupisa, chete nekushanda kunotonhora. Inogona kugadzirwa zviri nyore uye kugadziridzwa neyakajairwa chitoro kugadzira maitiro.
