SUS347 (347/S34700/0Cr18Ni11Nb) waa nooc bir ah oo leh birta austenitic ahama oo iska caabin wanaagsan u leh daxalka crystal.
Waxay leedahay caabbinta daxalka wanaagsan ee aashitada, alkali iyo dareeraha milixda, waxayna leedahay iska caabin oksaydh oo wanaagsan iyo alxanka hawada ka hooseysa 800 °C. 347 birta aan dahsoon waxay leedahay jebin heerkul sare oo heerkul sare ah (Stress Dill) waxqabadka iyo heerkulka sare ee iska caabinta cadaadiska guryaha ayaa ka fiican 304 birta aan la taaban karin. Si weyn loogu isticmaalo duulista, korantada, kimisteriga, kiimikaalka petrochemical, cuntada, waraaqaha iyo meelaha kale.
