SUS347 (347 / S34700 / 0Cr18Ni11Nb) o se ituaiga uʻamea ma austenitic uʻamea uʻamea ma lelei teteʻe i tioata corrosion.
E lelei le corrosion teteʻe i acid, alkali ma masima vai, ma e lelei oxidation tetee ma weldability i le ea i lalo ifo 800 °C.347 u'amea u'amea e sili atu le maualuga o le vevela o le motusia o le mamafa (Stress Rupture) faʻatinoga ma le maualuga o le vevela o le fetolofi teteʻe faʻamalosi mea faʻainisinia e sili atu nai lo le 304 uʻamea.Faʻaaogaina lautele i vaalele, gaosiga o le eletise, kemisi, petrochemical, meaai, pepa ma isi fanua.
