Inconel 625 is a nickel-chromium alloy enhanced with molybdenum and niobium, designed to tackle high-temperature and corrosive environments. Our spring wire meets ASTM B446 standards, ensuring top-notch quality for demanding 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 excellent strength and corrosion resistance 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 thrives in temperatures from -423°F (-253°C) to 1800°F (982°C), resisting oxidation and scaling even in extreme heat. This makes it ideal for springs and components that face intense thermal cycling and mechanical stress.
We craft our spring wire using advanced techniques like vacuum induction melting (VIM) and vacuum arc remelting (VAR), followed by cold drawing and heat treatments like solution annealing at 1700-1900°F. This ensures a uniform microstructure and excellent fatigue resistance, critical for springs in high-stress applications. Available in diameters from 0.005” to 0.125” and various tempers, our wire is customizable to fit your needs. It’s also highly weldable without post-weld heat treatment, making it perfect for complex assemblies like turbine springs or valve components.
