Alloy 321 (UNS S32100) o se titanium fa'amautu austenitic u'amea u'amea ma lelei fa'a'a'a'a lautele tete'e. O lo'o i ai le tete'e lelei i le fa'aleagaina o le va'aiga pe a uma ona fa'aalia i le vevela i le chromium carbide timuga o le 800 - 1500 ° F (427 - 816 ° C). O le u'amea e tete'e i le fa'ama'iina i le 1500°F (816°C) ma e maualuga atu le fetolofi ma fa'amamafa mea e malepe ai nai lo u'amea 304 ma le 304L. E iai fo'i ma'a'a lelei maualalo le vevela.
Alloy 321H (UNS S 32109) o le maualuga maualuga o le kaponi (0.04 - 0.10) faʻasologa o le uʻamea. Na atia'e mo le fa'aleleia atili o le fetolofi ma mo le malosi maualuga i le vevela i luga atu o le 1000oF (537°C). I le tele o taimi, o le kaponi o loʻo i totonu o le ipu e mafai ai ona faʻamaonia lua.
Alloy 321 e le mafai ona faʻamaʻaʻaina i togafitiga vevela, naʻo le galue malulu. E faigofie ona uelo ma fa'agaioiina i faiga masani fa'atauga a faleoloa.
