Vaega Autu

1. Malosi maualuga ma le maaa: 17-4 PH e mafai ona ausia le malosi maualuga ma le maaa e ala i togafitiga faʻamaʻaina-faʻafefe, faʻaoga talafeagai mo talosaga e manaʻomia ai le malosi maualuga.

2. Tete'e Lelei a'e: E ui lava e le pei o le u'amea e pei o austenitic u'amea u'amea pei o le 304 ma le 316, ae o lo'o ofoina mai pea le fa'a'a'a lelei i le tele o si'osi'omaga.

3. Lelei lelei:  E mafai ona uelo e faʻaaoga ai faiga faʻapipiʻi eseese. E fautuaina le togafitiga o le vevela post-weld e ausia ai mea sili ona lelei.

4. Lelei masini: E lelei machinability i le fofo-togafitiga tulaga ma e mafai ona faʻaleleia atili mea faʻainisinia pe a uma togafitiga vevela.
