Inconel 718 (UNS N07718): A Nickel Super Alloy Strengthened by Age Hardening<\/b><\/h3>\n

Technical Description<\/b><\/h3>\n

Inconel 718<\/span> is a nickel-based super alloy whose strength has been increased by age hardening. The typical composition of the alloy is 50-55% nickel<\/span>, 17-21% chromium<\/span>, 4.75-5.5% niobium + tantalum<\/span>, 2.8-3.3% molybdenum<\/span>, 0.65-1.15% titanium<\/span>, 0.2-0.8% aluminium<\/span> and up to 18.5% iron. This distinctive composition provides high temperature strength and excellent fatigue resistance.<\/p>\n

The most characteristic property of Inconel 718 is that it is suitable for precipitation<\/a> hardening<\/span>. With heat treatment, gamma prime and gamma double prime precipitates (\u03b3\u2019 \u2013 Ni\u2083(Al,Ti) and \u03b3\u201d \u2013 Ni\u2083Nb) are formed and its mechanical strength is significantly increased. Thanks to this property it exhibits high yield strength and creep resistance at temperatures up to 700 \u00b0C.<\/p>\n

The alloy has good weldability properties; in this respect it differs from other nickel alloys that show a tendency to cracking after welding (for example Inconel 625). The tensile strength<\/span> of Inconel 718 is approximately 1240 MPa, and its yield strength<\/span> is at a level of 1030 MPa.<\/p>\n
