Inconel 718 Springs
ASTM B637, UNS N07718
Inconel 718 Springs are age hardened springs with good corrosion resistance. Inconel 718 Springs are good for use in elevated temperature applications with no magnetism. Torqbolt is a prominent Inconel 718 Spring supplier in India.
Inconel® 718 is an age-hardenable Nickel-Chromium-Columbium (Niobium)-Molybdenum alloy with high strength, corrosion-resistance, and good fabrication characteristics. Inconel® 718 has high tensile, yield, and creep-rupture properties at high temperatures and can operate at cryogenic temperatures up to 1200°F (650°C). It has higher strength than Inconel X-750 and better mechanical properties at lower temperatures than Nimonic 90 and Inconel X-750.
Inconel® 718 is also known as Nicrofer 5219, Superimphy 718, Haynes 718, Pyromet 718, Supermet 718. and Udimet 718.
