O le Ti o le 321 stainless steel o loʻo i ai o se elemene faʻamautuina, ae o se uʻamea malosi foi, e sili atu nai lo le 316L.321 u'amea u'amea lelei abrasion teteʻe i acids organic ma inorganic acids o concentrations eseese ma vevela, aemaise lava i oxidizing ala o faasalalauga, lea e faaaoga e gaosia ofu-tetee acid containers ma ofi-tetee meafaigaluega linings ma pipelines.
321 uʻamea uʻamea o Ni-Cr-Ti austenitic uʻamea uʻamea, o lona faatinoga e talitutusa lava ma le 304, ae ona o le faaopoopoga o le titanium uʻamea, ina ia sili atu saito tuaoi corrosion tetee ma maualuga vevela malosi.Ona o le faʻaopoopoga o le titanium metal, e pulea lelei le faʻavaeina o le chromium carbide.
321 u'amea u'amea e sili atu le maualuga o le vevela Fa'amamafa Fa'atinoga male vevela ma le maualuga o le vevela.E fetaui lelei mo vaega uelo faʻaaogaina i le vevela maualuga.
