Haynes 718 Welding Wire is mainly made up of nickel (~50–55%), chromium (17–21%), iron (the balance), niobium (4.75–5.5%), and molybdenum (2.8–3.3%), along with some titanium, aluminum, and trace elements. This precipitation-hardenable alloy boasts impressive tensile strength of ≥1240 MPa, yield strength of ≥1030 MPa, and elongation of ≥12–18%. It maintains high mechanical stability up to 700°C and shows excellent resistance to stress corrosion cracking, creep rupture, and oxidation. Plus, it offers great weldability with minimal cracking, making it ideal for high-stress and cyclic loading applications in critical systems.
