 Applications:

Alloy 625 through softening and annealing is widely used in the chemical process industry and Offshore & marine occasion or bearing high mechanical stress. It’s highly resistant to corrosion and high strength make it can be used as a thinner structural part. The typical applications are:

  1. Components of an organic chemical process containing chlorides, especially in the use of acid chloride catalysts
  2. Digesters and bleaching tanks for the pulp and paper industries;
  3. Absorption tower, reheater, flue gas inlet baffle, fan (moisture), mixer, flow guide plate, flue gas flue gas flue gas desulfurization system, etc;
  4. Equipment and components used in the manufacture of acidic gas environments;
  5. Acetic acid and acetic anhydride reaction generator;
  6. Sulfuric acid condenser.
