Inconel 718 Fasteners Manufacturer
Alloy 718 (UNS N07718, W Nr 2.4668) is a high-strength, heat-resistant and corrosion-resistant nickel-based alloy composed of nickel, chromium, molybdenum, iron, aluminum, titanium and niobium. Due to its excellent properties, high yield tensile and creep-rupture properties at temperatures up to 1300ºF and oxidation resistance to 1800ºF. This alloy has a wide range of applications in aerospace, energy, automotive manufacturing and chemical industries
