SUS347 (347 / S34700 / 0Cr18Ni11Nb) ni ubwoko bwibyuma bifite ibyuma bya austenitike bitagira umuyonga kandi birwanya neza ruswa.
Ifite ruswa irwanya aside, alkali n'amazi y'umunyu, kandi ifite imbaraga zo kurwanya okiside hamwe no gusudira mu kirere kiri munsi ya 800 ° C.347 ibyuma bitagira umuyonga bifite ubushyuhe buhebuje bwo guhagarika ubushyuhe (Stress Rupture) hamwe nubushyuhe bwo hejuru bwo guhangana nubushyuhe bwimikorere iruta ibyuma 304.Ikoreshwa cyane mu ndege, kubyara ingufu, chimie, peteroli, ibiryo, impapuro nizindi nzego.
