Ang SUS347 (347/S34700/0Cr18Ni11Nb) ay isang uri ng bakal na may austenitic stainless steel na may magandang pagtutol sa crystal corrosion.
Ito ay may magandang corrosion resistance sa acid, alkali at salt liquid, at may magandang oxidation resistance at weldability sa hangin sa ibaba 800 °C. Ang 347 stainless steel ay may mahusay na high temperature stress breaking (Stress Rupture) na pagganap at mataas na temperatura creep resistance stress mechanical properties ay mas mahusay kaysa sa 304 stainless steel. Malawakang ginagamit sa aviation, power generation, chemistry, petrochemical, pagkain, papel at iba pang larangan.
