What is High Temperature 347H Stainless Steel ?
347H has good intergranular corrosion resistance, and has good corrosion resistance in alkali, seawater and various acid solutions. Due to its good heat resistance and oxidation resistance, it can withstand small loads at temperatures below 850 degrees.

High Temperature 347H Stainless Steel Good For:
Due to the stabilizing element Nb, its resistance to intergranular corrosion and polysulfuric acid intergranular stress corrosion resistance is good. In acid, alkali, salt and other corrosive media, its corrosion resistance is similar to that of 18-8 austenitic stainless steel containing Ti. Therefore, it is widely used in boiler, power generation, petroleum, chemical, synthetic fiber, food, paper and other industries. Heat exchangers for superheater tubes, reheater tubes, steam piping and petrochemicals in large boilers.
