Executive 625 is a nickel-chromium-molybdenum alloy designed for welding alloy 625 and alloy 825 using TIG, MIG and SAW welding processes. This alloy is also used for many dissimilar Inconel® alloy joints and weld overlay. The high alloy content of Executive 625 produces high strength weld material with excellent corrosion resistance at elevated service temperatures. The increased level of molybdenum offers excellent resistance to stress corrosion cracking, pitting, and crevice corrosion. The low iron content of Executive 625 also makes it an excellent choice for overlay applications and has an operating range from cryogenic to beyond 1000°F (540°C). Executive 625 filler metal is produced using high quality raw materials and tightly controlled chemistry to provide top quality, exceptionally clean wires that deliver the results fabricators demand. Use Executive 625 FC where flux cored wire is suited to the application.
Application and Features
Executive 625 is a versatile filler metal that is used to weld dissimilar joints between nickel-chrome-molybdenum alloys and stainless, carbon or low alloy steels. It is also used when welding various nickel alloys such as 9% nickel steel, Monel®, Inconel®, 254SMO, and AL-6XN. Executive 625 is used extensively for overlay applications as well due to its restricted low iron content which ensures the highest corrosion standard for these applications.
This wire is also suitable for laser welding and WAAM applications (Wire Arc Additive Manufacturing, aka Metal 3D printing).
