Inconel® 625 Coil

Inconel® 625 Coil is a nickel–chromium–molybdenum alloy known for its exceptional resistance to oxidation, fatigue, and chloride-induced stress corrosion cracking. Its coil form ensures uniformity and continuous feedstock for fabrication processes, making it highly adaptable for manufacturing large-scale industrial components. This alloy is widely used in aerospace, marine, and chemical processing industries, particularly for heat exchangers, marine exhaust systems, and environmental control units. Specific applications include wire arc additive manufacturing feedstock, chemical plant ducting, and marine structures exposed to seawater, where superior corrosion resistance and fatigue performance are crucial. Research has explored its tribological performance with micro-textures for improved wear resistance, heat treatment effects on microstructure and ductility, and optimization of machining techniques such as WEDM for precision manufacturing. The combination of mechanical durability, corrosion resistance, and adaptability in continuous coil form underscores Inconel® 625 Coil’s importance in advancing both scientific applications and industrial technologies.
