TP347H (1Cr19Ni11Nb) is a high-carbon niobium-containing Cr-Ni austenitic stainless steel. Because it contains the stabilizing element Nb, it has good resistance to intergranular corrosion and polysulfuric intergranular stress corrosion. It is in acid, alkali, salt and other corrosive media. Its corrosion resistance is similar to 18-8 austenitic stainless steel containing Ti, so it is widely used in boiler, power generation, petroleum, chemical, synthetic fiber, food, paper and other industries. Superheater tubes, reheater tubes, steam pipes and petrochemical heat exchangers for large boilers.
