Machining stainless steel grade 317L e manaʻomia le maualalo o saosaoa ma fafaga faifaipea e faʻaitiitia ai lona uiga e galue faʻamalosi.O lenei u'amea e sili atu le malosi nai lo le vasega 304 u'amea u'amea fa'atasi ai ma se va'a manoa umi;ae ui i lea, e fautuaina le faʻaaogaina o masini vaʻaia.E mafai ona fa'atinoina le uelo e fa'aaoga ai le tele o auala fa'afefiloi ma fa'asagaga masani.Oxyacetylene uelo e tatau ona aloese.AWS E/ER 317L fa'atumu uamea ua fautuaina.
E mafai ona fa'atinoina faiga masani o galuega vevela.O mea e tatau ona faʻamafanafanaina i le 1149-1260 ° C (2100-2300 ° F);ae peitai, e le tatau ona faavevela i lalo ole 927°C (1700°F).Ina ia fa'amalieina le fa'a'ele'ele, e fautuaina le fa'amuta pe a mae'a galuega.
O le seleina, fa'ailoga, ulutala ma le tusi e mafai i le vasega 317L u'amea u'amea, ma e fautuaina le fa'amuta pe a mae'a galuega e fa'aitiitia ai fa'alavelave i totonu.O le fa'amaluluina e faia i le 1010-1121°C (1850-2050°F), lea e tatau ona soso'o ai ma le fa'amalie vave.
Vasega 317L uamea e le tali atu i togafitiga vevela.
Talosaga
Vasega 317L uamea u'amea fa'aaoga lautele i talosaga nei:
- Condenser i fossil
- O le gaosiga o pulu ma pepa
- Fale faaniukilia e fau ai eletise
- Mea faigaluega fa'agasologa o vaila'au ma petrochemical.
