Our spring wire meets the rigorous AMS 5667 and ASTM B637 standards, ensuring top-tier quality for demanding applications. With a composition of approximately 70% nickel, 14-17% chromium, 2.25-2.75% titanium, and 0.7-1.2% aluminum, it has a density of 8.28 g/cm³ and a melting range of 1393°C to 1427°C. This alloy is built to handle extreme environments, from cryogenic lows of -423°F (-253°C) to highs of 1300°F (704°C).
Our Inconel X750 spring wire offers impressive mechanical properties: a minimum tensile strength of 160 ksi (1103 MPa), yield strength of 100 ksi (689 MPa), and 15% elongation at room temperature. It’s designed to resist relaxation and creep at high temperatures, making it ideal for springs in heat-intensive applications. It also provides excellent corrosion resistance, standing up to oxidation, stress-corrosion cracking, and aggressive chemicals like acids and hot gases.
We produce our spring wire using advanced processes like vacuum induction melting (VIM) and vacuum arc remelting (VAR), followed by cold drawing, solution annealing at 1800-1900°F, and age hardening at 1150-1350°F. This ensures a fine microstructure and superior fatigue resistance, critical for springs under constant stress and thermal cycling. Available in diameters from 0.005” to 0.125” and various tempers, our wire is customizable to fit your project. Its weldability with proper techniques makes it versatile for complex assemblies like turbine springs or heat exchanger components.
