ASME B18.2.2 Hex Nuts Inconel 718 and Incoloy 800 800H 800HT Nuts 2.4668 Nuts Nickel Alloy N07718 Nuts
Inconel 718 fasteners have been used in environments from -400o F (-250o C) to 1300o F (700o C). Typical applications include gas turbine parts and cryogenic storage tanks.
Alloy 718 for aerospace and power generation is heat treated to provide maximum strength and high creep resistance, with typical hardness values in excess of 42HRC. Primary applications are components for gas turbines, aircraft engines, fasteners and other high-strength applications. Additionally, Inconel 718 meets ASTM B637, A1014, UNS N07718 and DIN EN 2.4668 specifications for high yield strength, excellent resistance to corrosion, oxidation and heat for high temperature bolting applications up to 1000o C (1800o F).
