Inconel Alloy 718 Tube

 

Product Description

Inconel Alloy 718 (UNS N07718/W.Nr. 2.4668) is a robust nickel-chromium alloy renowned for its exceptional strength and resistance to corrosion, making it suitable for use in extreme temperatures ranging from -423°F to 1300°F. This age-hardenable material is highly versatile and can be easily fabricated into intricate components.

 

Widely utilized in the aerospace industry, this nickel-chromium-molybdenum superalloy is a key material for manufacturing hot section parts of turbine blades, ducting systems, and engine exhaust systems. Remarkably, nickel-based superalloys like Inconel 718 account for approximately 50% of the materials used in aircraft and rocket engines.

 

Inconel Alloy 718 tubes are particularly well-suited for applications such as hot extrusion tooling and various high-performance parts, including rings, fasteners, casings, and instrumentation components. They are also commonly used in the production of nuclear fuel element spacers and high-strength bolts, showcasing their adaptability and reliability in demanding environments.

 

 

Properties of Inconel 718

• High Strength: Maintains excellent mechanical properties at both high and low temperatures.
• Corrosion Resistance: Resists oxidation, corrosion, and pitting in harsh environments.
• Temperature Resistance: Performs well in temperatures ranging from cryogenic up to 1300°F (704°C).
• Weldability: Can be welded using common techniques, though post-weld heat treatment is often required.

Manufacturing Standards

• Inconel 718 tubes are manufactured to meet various industry standards, including:
• ASTM B161: Standard for nickel seamless pipe and tube.
• ASTM B516: Standard for welded nickel and nickel-cobalt alloy tubes.
• AMS 5596: Aerospace Material Specification for seamless tubes.

 

Common Sizes and Forms

• Seamless and Welded Tubes: Available in both forms depending on the application.
• Sizes: Range from small diameters (e.g., 1/8 inch) to larger diameters (e.g., several inches), with varying wall thicknesses.

 

Heat Treatment

• Inconel 718 is typically supplied in the annealed condition and can be age-hardened to achieve higher strength. Common heat treatment processes include:
• Solution Annealing: Heating to 1700-1850°F (927-1010°C) followed by rapid cooling.
• Aging: Heating to 1325-1350°F (718-732°C) for 8 hours, then furnace cooling to 1150°F (621°C) and holding for a total aging time of 18 hours.

 

Machining and Fabrication

• Machining: Requires specialized techniques due to its high strength and work-hardening characteristics.
• Fabrication: Can be formed, welded, and joined using standard methods, though care must be taken to avoid contamination and ensure proper heat treatment.
