SUS347 

 SUS347 (18Cr-9Ni-Nb) with Nb, to improve resistance to intergranular corrosion. SUS347 (347/S34700/0Cr18Ni11Nb) has good resistance to grain austenitic stainless steel to corrosion. In acid, alkali, salt solution have good corrosion resistance, the following air at 800 ℃ with good oxidation resistance and weldability. 347 stainless steel with excellent high-temperature stress rupture (Stress Rupture) performance and high-temperature creep resistance properties (Creep Resistance) stress mechanical properties are superior to 304 stainless steel. Widely used in aerospace, power generation, chemical, petrochemical, food, paper and other fields.
