SUS347 (18Cr-9Ni-Nb) containing Nb, to enhance the resistance to intergranular corrosion resistance.
SUS347 (347/S34700/0Cr18Ni11Nb) has excellent resistance to corrosion properties of austenitic stainless steel crystal. Have good corrosion resistance in acid, alkali, salt solution, 800 degrees below the air may have good antioxidant properties and welding performance. 347 stainless steel has excellent high temperature stress rupture (Stress Rupture) properties and high temperature creep resistance properties of (Creep Resistance) stress mechanical properties are better than 304 stainless steel. Widely used in aviation, power generation, chemical, petrochemical, food, paper etc..
