AMS 5663: Specifications for Inconel 718 bars, forgings, and rings

2024-11-12

The AMS 5563 specification defines the requirements for the round bar made from Inconel 718 material. This AMS 5563 standard includes chemical composition, mechanical properties, heat treatment, and other quality control measures. The Inconel 718 round bar is available in various diameters and lengths, and it is typically produced by hot rolling or cold drawing.

At Lork Group, we are pleased to offer Inconel 718 bars, a high-strength, nickel-chromium-based superalloy designed for exceptional resistance to oxidation, corrosion, and thermal fatigue at elevated temperatures. Known for its impressive performance under extreme conditions, Inconel 718 (UNS N07718) is a preferred choice for the aerospace, oil and gas, and power generation industries.

Key Features of Inconel 718 Alloy Bars

High Tensile and Creep Strength: Inconel 718 maintains high strength and toughness at temperatures up to 1,300°F (700°C), suitable for applications requiring durability and resistance to deformation under stress.

Corrosion and Oxidation Resistance: Inconel 718 excellent resistance to a wide range of corrosive environments and aggressive chemical compounds, including sulfur and salt.

Weldability: Inconel 718 is highly weldable and maintains its strength post-welding without the need for post-weld heat treatment.

Thermal Stability: Inconel 718 outstanding stability at high temperatures, making it ideal for thermal cycling environments and applications requiring consistent performance.

UNS N07718 Inconel 718 Bar Applications

The high-temperature capabilities of AMS 5563 inconel 718 round bar make it an ideal material for high-temperature applications. For example, this n07718 material is used in the manufacture of gas turbine engine components such as blades, discs, and casings. Inconel 718 AMS 5663 Round Bar is also used in the construction of rocket motors, where it provides excellent resistance to high temperatures, pressure, and corrosion.
