Uamea uʻamea - Vasega 347H (UNS S34709) vailaʻau vailaʻau

Folasaga

O u'amea lamolemole o u'amea maualuga ia e maualuga le tete'e atu nai lo isi uamea ona o le i ai o le tele o chromium i le va o le 4 i le 30%.Ua fa'avasegaina u'amea uamea i martensitic, ferritic ma austenitic e fa'atatau i lo latou fausaga tioata.I le faaopoopo atu, latou te faia se isi vaega ua taʻua o uʻamea-malosi uamea, o se tuufaatasiga o uamea martensitic ma austenitic.

O fa'amaumauga o lo'o mulimuli mai o le a maua atili ai fa'amatalaga e uiga i le vasega 347H u'amea u'amea, lea e fai si faigata nai lo vasega 304 sila.
