Chung Metal offers Haynes 718 Bars and Rods, a nickel‑based superalloy of high strength for high temperature, creep, and corrosion resistance service. Age‑hardenable Alloy 718 has strength to approximately 650 °C. Our bars and rods are heat treated with controlled heat treatment or forged and wrought, with resulting excellent mechanical properties, toughness, and thermal cycle stability. They find wide usage in aerospace, power generation, and gas turbine service.
Haynes 718 has ~50‑55% nickel, ~17‑21% chromium, ~4.75‑5.50% niobium + tantalum, ~2.8‑3.3% molybdenum, with minor aluminium, titanium. Tensile strength after solution annealing and aging can be greater than ~1,100 MPa; yield strength similarly high; elongation in good condition; improved creep and fatigue resistance. Density ~8.19 g/cm³. Excellent oxidation and corrosion resistance in high temperature conditions.
Haynes 718 rods are available in various sizes, typically ranging from 0.125 inches (3.175 mm) to 4 inches (101.6 mm) in diameter, with lengths customizable based on customer requirements.
Yes, Haynes 718 rods can be customized in size and length according to specific requirements. Manufacturers often provide custom machining or cutting services to meet the desired specifications.
Haynes 718 bars and rods perform exceptionally well in high-temperature environments, maintaining strength, resistance to oxidation, and excellent fatigue properties up to 1300°F (704°C), making them ideal for aerospace applications.
Used in turbine discs, shafts, bolts, seals, jet engine components, exhaust systems, combustion chambers, nuclear reactor fasteners, and other parts subject to high temperature and mechanical stress. Also for aerospace structural components, chemical processing plant high temperature pressure vessels, and wherever strength at high temperature is critical. Offers superior versatility for hostile environments.
