1.309s vasega uamea uamea
faʻailoga tutusa i Saina o le 06Cr23Ni13;Amercia Standard S30908, AISI, ASTM;JIS G4305 tulaga masani sus;tulaga Europa 1.4833.
O le 309s o lo'o i ai le sulfur free cuting stainless steel, fa'aaogaina mo le tipiina e leai se totogi ma le susulu/mama mama taimi faigata.
309 s e maualalo le carbon anotusi fesuiaiga o 309 uʻamea uʻamea, uelo e faʻaaogaina i le taimi.Low carbon anotusi e faia i le vevela afaina sone latalata i le uelo i le timuga o carbide i se tulaga maualalo, ma e mafai ona iu i timuga o carbide stainless uamea intergranular corrosion i nisi siosiomaga (ulding erosion).
2.309S Fa'apitoa
E mafai ona tatalia le faʻavevela faifai pea i lalo o le 980 ℃, e maualuga atu le malosi ma le faʻamaʻiina o le faʻamaʻi, maualuga le vevela o le faʻatinoga o le carburizing.

5.309S Talosaga
309s o mea e fa'aogaina ai le ogaumu.
309s o loʻo faʻaaogaina lautele i pusa, malosi (malosi faaniukilia, mana vevela, suauʻu suauu), ogaumu fale gaosimea, afi afi, ogaumu faʻavevela, vailaʻau, petrochemical ma isi vaega taua.
