INCONEL 718 Per BMS7-340
BMS7-340 is the Boeing Material Specification for the alloy INCONEL 718, a superalloy from the UNS Alloy Number N07718 family. It covers a variety of product forms for the alloy, including bars, forgings, rings, and more. BMS7-340 outlines the requirements for the chemical composition, mechanical properties, and heat treatment for the alloy to provide consistent superior service in aircraft engines and structural components.
Fighter Jet Metals works with Aerospace OEMs to maintain the BMS7-340 specification for Nickel 718 Forgings. If you are currently managing a project that requires BMS7-340 please reach out to us so we can assist.
Material Overview
INCONEL 718 per BMS7-340 is an austenitic, precipitation-hardenable nickel-chromium alloy known for:
- Superior fatigue strength and stress corrosion resistance
- High yield strength and creep resistance up to 1300°F (704°C)
- Outstanding weldability with low risk of post-weld cracking
- Excellent oxidation resistance up to 1800°F (982°C)
These properties make it ideal for aerospace components requiring strength, toughness, and reliability under extreme conditions.
