Introduction
Inconel 625 (Alloy 625, 2.4856, UNS N06625) nickel-based alloy tube and tubing
INCONEL 625 is a Nickel-Chromium-Molybdenum-Columbium (Niobium) alloy with a pure austenitic structure in the solid solution state. It has excellent strength at temperatures up to 1500°F (816°C) and is resistant to a variety of corrosive media. Inconel 625 has the advantages of high strength, good workability (including welding), and corrosion resistance. Operating temperatures range from low temperatures to 1800°F (982°C). Inconel 625 alloy derives its strength from the reinforcing effect of molybdenum and niobium on its nickel-chromium matrix, and therefore does not require precipitation hardening treatment. The alloy has both good corrosion resistance, oxidation resistance and high strength, as well as good formability and toughness. It is suitable for use where both high corrosion resistance and high strength are required to match.

Inconel 625 tubes & pipes application:
Alloy 625 has both high corrosion resistance and good thermal strength, so it can be used as both a corrosion-resistant alloy and a thermal strength alloy. In general, Inconel 625 alloy is mainly used for corrosion resistance of HNO 3, HNO 3 + H 2 SO 4, HNO 3 + HF mixed acid and wet phosphoric acid containing H 2 SO 4 and F-, Cl-, and seawater corrosion resistance, etc.; while Inconel 625 Plus alloy has similar corrosion resistance to Inconel 625 alloy in acid medium and seawater. In addition to corrosion resistance in acid media and seawater, Inconel 625 Plus alloy has excellent resistance to chloride and sulfide stress corrosion as well as pitting and crevice corrosion, even in the aging state. Both alloys can be used as corrosion-resistant, high-strength materials to manufacture towers, tanks, vessels, pipelines, as well as reactors, heat exchangers, valve parts, etc.
