Aotelega o le Paipa Uamea e le gaoia le 321
I le avea ai o se fa'aliliuga ua toe fa'aleleia o le SS304, o le u'amea e le gaoia 321 (SS321) o se u'amea e le gaoia austenitic ua fa'amautu fa'atasi ai ma se fa'aopoopoga titanium e le itiiti ifo i le 5 taimi le aofa'i o le kaponi. O le fa'aopoopoga titanium e fa'aitiitia pe taofia ai le fa'a'ono'onoina o le carbide precipitation i le taimi o le uelo ma i auaunaga i le va o le vevela o le 425-815°C. E fa'aleleia atili ai fo'i nisi o meatotino i le vevela maualuga. E maua ai e le SS321 le tete'e mata'ina i le oxidation ma le ele ma e malosi lelei le creep. E fa'aaogaina tele i masini fa'amama suau'u, paipa pressure vessel, radiant super heater, bellews, ma masini togafitiga vevela maualuga.

Malosiaga o le Vaivai o le Paipa U'amea e le gaoia le 321
I faʻaoga faʻaonaponei, e taua foʻi le mafaufau i le malosi o le vaivai. Ma i lenei itu, e iai sina lelei o le 321 SS nai lo le 304 SS. O tapulaʻa o le vaivai poʻo le tumau (malosi i le punou) o uʻamea e le gaoia austenitic i le tulaga faʻamafanafana e tusa ma le afa o le malosi o le tensile. O tapulaʻa masani o le tensile ma le tumau mo nei uʻamea faʻafefiloi (faʻamafanafana) o loʻo tuʻuina atu i le laulau o loʻo i lalo:
| U'amea fa'a'ofuofu | Tete'e Masani | Tapula'a Masani o le Tumau |
| 304L | 68 ksi | 34 ksi |
| 304 | 70 ksi | 35 ksi |
| 321 | 76 ksi | 38 ksi |
Malosiaga o le fa'apipi'iina o le 321 Stainless Steel Tube
E matuā lelei le fa'avevela o le SS321 ma le TP321, e le mana'omia se fa'avevela muamua. E mana'omia ona tutusa le tu'ufa'atasiga o le mea e fa'atumu ai ae maualuga le aofa'i o le u'amea fa'afefiloi. Mavaevae o le liquation i le sone ua a'afia i le vevela: maualalo le malosi e ulufale mai. Tele o le fatu manifinifi. Ferrite ≥ 5%.
O u'amea fa'atumu fautuaina o le SS 321, 347, ma le 348. O le eletise o le E347 po'o le E308L [vevela tautua < 370 °C (700 °F)].
Fa'aoga o le 321 Stainless Steel Tube
E mafai ona fa'aaogaina le ituaiga 321, 321H ma le TP321 i nofoaga e le mafai ai ona fa'aogaina ni vaila'au pe a uma ona fa'apipi'i, e pei o paipa ausa ma paipa fa'avevela tele ma faiga e alu ese ai le ea i afi fe'avea'i ma turbine kesi e amata mai le vevela mai le 425 i le 870 °C (800 i le 1600 °F). Ma paipa fa'apipi'i suau'u ma faiga hydraulic mo va'alele ma ta'avale va'alele.
