The softened low-carbon alloy 625 is widely used in the chemical process industry, its good corrosion resistance and high strength make it suitable a thinner structural component. Alloy 625 can be applied in situations where it is in contact with seawater and is subjected to high mechanical stresses. Typical areas: 1. Components for organic chemical process plants containing chlorides, especially where acidic chloride catalysts are used. 2. For the manufacture of dig and bleach tanks for the pulp and paper industry. 3. Absorption towers, reheaters, flue gas inlet dampers, fans (wet), agit, deflectors, and flue gas ducts in flue gas desulphurisation systems. 4. For the manufacture of equipment and parts for use in acid environments. 5. Acetic and ethyl alcohol reaction generators. 6. Sulphuric acid condensers.
