400 fa'asologa ma le 300 fa'asologa u'amea u'amea e lua fa'asologa u'amea masani, ma o lo'o i ai ni eseesega taua i le tuufaatasiga ma le faatinoga. O nisi nei o eseesega autu i le va o le 400 series ma le 300 series stainless steel rods:
| Uiga | 300 Fa'asologa | 400 Fa'asologa |
| Tulaga Alloy | Austenitic u'amea u'amea ma maualuga nickel ma chromium anotusi | Ferritic po'o martensiti u'amea u'amea i lalo ifo nickel i totonu ma maualuga chromium |
| Tete'e a'e | Lelei le corrosionresistance, talafeagai mo siosiomaga corrosive | Fa'alaloina le fa'afefeteina fa'atusatusa i le 300series, talafeagai mo fa'aoga lautele tau alamanuia |
| Malosi ma le maaa | Malosi maualuga ma le maaa, talafeagai mo talosaga maualuga-stress | E masani ona maualalo le malosi o le eleele pe a faatusatusa i le 300 faasologa, maualuga le maaa i nisi vasega |
| Meatotino maneta | Ole tele ole fa'amaneta | E masani ona maneta ona o le fausaga martensitic |
| Talosaga | gaosiga o mea'ai, meafaigaluega faafoma'i, alamanuia kemikolo | Fa'aaogāga fa'apisinisi lautele, fa'au'u ta'avale ta'avale, mea umukuka |
