Inconel 625 is a nickel-chromium alloy packed with molybdenum and niobium, designed to thrive in harsh chemical processing environments. Our spring wire meets the stringent ASTM B446 standard, ensuring top-tier performance for critical applications. With a composition of 58% minimum nickel, 20-23% chromium, 8-10% molybdenum, and 3.15-4.15% niobium, it has a density of 8.44 g/cm³ and a melting range of 1290°C to 1350°C. This alloy is a powerhouse, offering exceptional corrosion resistance and strength across a wide temperature range.
Our Inconel 625 spring wire delivers impressive mechanical properties: a minimum tensile strength of 120 ksi (827 MPa), yield strength of 60 ksi (414 MPa), and 30% elongation at room temperature. It performs reliably from -423°F (-253°C) to 1800°F (982°C), resisting oxidation and scaling in high-heat conditions. Its standout feature is its corrosion resistance, handling pitting, crevice corrosion, and stress-corrosion cracking in aggressive media like acids, alkalis, and seawater.
We craft our spring wire using advanced processes like vacuum induction melting (VIM) and vacuum arc remelting (VAR), followed by cold drawing and solution annealing at 1700-1900°F. This ensures a uniform microstructure and excellent fatigue resistance, critical for springs in demanding chemical processing applications. Available in diameters from 0.005” to 0.125” and various tempers, our wire is customizable to fit your project. Its high weldability, without needing post-weld heat treatment, makes it ideal for complex assemblies like reactor springs or valve components.
