321 321H Stainless hlau yog titanium-stabilized version ntawm 304 rau cov kev siv tshwj xeeb hauv qhov kub thiab txias. Nws tsis kam mus rau rhiab heev, ua ke nrog nws lub zog siab dua ntawm qhov kub thiab txias, ua rau nws haum rau cov ntawv thov uas 304 yuav rhiab heev lossis 304L thermal zog tsis txaus. Weld rot intergranular corrosion tsis tshwm sim thaum raug rau ib puag ncig me me corrosive. Txawm li cas los xij, vuam 321 yuav tsum tsis txhob siv nyob rau hauv ib puag ncig oxidized heev, vim tias nws raug rau "riam kab" yaig. Txawm li cas los xij, hauv kev ua haujlwm kub ntau dua 500 ° C, 321 yog qhov kev xaiv zoo dua thiab yog li nws muaj nws tus kheej zoo. Alloy 321 stainless hlau yeeb nkab vim nws cov khoom siv zoo, kuj ua rau kev siv kub. Alloy 321 stainless hlau muaj ntau dua creep thiab kev ntxhov siab tawg cov yam ntxwv dua li alloy 304, thiab alloy 304L tshwj xeeb kuj tseem raug txiav txim siab rau cov teeb meem rhiab thiab intergranular corrosion.
