Inconel 625 Pipe Description

The strength of Inconel 625 pipe comes from the solid solution strengthening effect of molybdenum and niobium contained in the nickel-chromium alloy. These elements also give the alloy excellent corrosion-resistant properties. While the pipe is designed for strength in high-temperature environments, its highly alloyed composition gives it a high degree of resistance to general corrosion as well as resistance to a wide range of oxidizing and non-oxidizing environments. The chromium and molybdenum content make the pipe highly resistant to corrosion spots caused by chloride ions, and the high nickel content steps up the alloy's resistance to chloride stress corrosion cracking. The material is highly formable and easier to weld than many nickel-based alloys. Even under welded conditions, the pipe still has the ability to resist intergranular corrosion, aside from corrosion and oxidation resistance.
