Inconel 625 stainless steel seamless capillary tubes exhibit excellent corrosion resistance to various corrosive media in both oxidizing and reducing environments, along with outstanding resistance to pitting and crevice corrosion. They do not suffer from stress corrosion cracking caused by chlorides and possess superior resistance to corrosion by inorganic acids. They offer good machinability and weldability, with no susceptibility to post-weld cracking, and are certified for the manufacture of pressure vessels with wall temperatures ranging from -196°C to 450°C.

The low-carbon alloy Inconel 625 stainless steel seamless capillary tubes, after softening annealing, are widely used in the chemical processing industry. Their excellent corrosion resistance and high strength make them suitable as thin structural components. Alloy 625 can be applied in environments involving contact with seawater and high mechanical stress. Typical application areas include:

1. Components in organic chemical processes involving chlorides, especially where acidic chloride catalysts are used.

2. Manufacture of digesters and bleaching tanks in the pulp and paper industry.

3. Absorbers, reheaters, flue gas inlet dampers, fans (wet), agitators, baffles, and flues in flue gas desulfurization systems.

4. Equipment and components used in acidic gas environments.

5. Acetic acid and acetic anhydride reaction generators.
