Inconel 718 Round Bar
Inconel 718 is a nickel-chromium alloy that contains supplemental amounts of columbium, iron, molybdenum, aluminum, and titanium. Given this alloy's durability and ductility characteristics, it has a wide range of applications in a broad spectrum of industries.
Common uses of nickel alloy 718
- Deployment in gas turbines
- Subsurface safety valves
- Aircraft engines
- Thrust Reversers
- Industrial fasteners
Performance of Nickel Alloy 718
Nickel alloy 718 provides the following universal performance characteristics:
- Good weldability & formability
- High durability in environments with temperatures of up to 1300° F
- Excellent oxidation resistance
- Superior cryogenics properties
Specifically, alloy 718 effectively resists stress rupture and creep when exposed to temperatures as hot as 1300°F, and maintains corrosion resistance below the 1800° threshold. Moreover, its tensile strength and impact resistance remain intact at temperatures in the cryogenic range, making it particularly useful for aerospace applications.
Alloy 718 is classified as "age-hardenable," meaning that its resistance properties increase over time—especially with prolonged exposure to cold temperatures. Numerous AMS and NACE specification processes can be deployed to customize its application-specific performance characteristics. Additionally, heat treatments can be used to soften the alloy prior to welding, forming or machining. Its machinability rating is 12% of B-1112, and it has typical stock removal rates of 20 surface feet per minute with high-velocity tools and 80 surface feet per minute with carbide tools.
