347/347H Stainless Steel Sheet

347/347H stainless steel sheet is an austenitic stainless steel plate with good corrosion resistance and high temperature performance. Compared with 304 and 321 stainless steel, 347/347H stainless steel plate has higher high temperature strength and plasticity, which is suitable for applications in high temperature and corrosive environments. This kind of stainless steel plate is widely used in aviation, petrochemical, food, paper and other industries, such as the exhaust manifold and branch pipe of aviation engine, hot gas pipeline of turbo compressor, and parts working under small load and temperature not exceeding 850℃. In addition, 347/347H stainless steel plate has good microstructure stability, uniform chemical composition, machinability and weldability, and has high dimensional accuracy and surface quality.

    Application

    The application of 347/347H Stainless Steel Sheet

    Firstly, it is widely used in boiler, power generation, petroleum, chemical, synthetic fibre, food, paper and other industries. This steel plate is also widely used in large boiler superheater tubes, reheater tubes, steam pipes and heat exchangers in petrochemical industry.

    Secondly, it has good resistance to intergranular corrosion and intergranular stress corrosion of polysulfuric acid due to the presence of the stabilising element Nb. This makes it resistant to corrosive media such as acids, alkalis and salts, thus extending the service life of the equipment.

    In addition, because Nb is less susceptible to burnout than Ti, it can also be used as a welding core for welding chromium-nickel austenitic stainless steels. This means that it is not only suitable for direct equipment manufacturing, but can also play a role in the repair and welding process.
