Inconel 718 Forging: High-Strength Aerospace & Energy Components

The Tier-1.5 Forging Advantage: From Billet to Finished Part

Traditional supply chains are fragmented, forcing you to manage separate forge and machine shops. ForceBeyond’s Tier-1.5 model integrates Inconel 718 Forging with our precision Inconel 718 Machining centers.

By taking total ownership of the metallurgical lifecycle, we ensure:

• Controlled Grain Flow: Optimizing the forging process to align grain flow with the part’s primary stress axes.
• Reduced Buy-to-Fly Ratio: Near-net-shape forging techniques that minimize raw material waste and machining cycle times.
• Single-Source Traceability: Full heat-lot documentation from the initial melt through forging, heat treatment, and final NDT.

While our forging process optimizes grain flow for high-stress rotating components, parts with extremely complex internal cooling channels or non-symmetrical housings may be better suited for our Inconel 718 Casting solutions utilizing Vacuum Induction Melting (VIM).

Why Forged Inconel 718?

Inconel 718 is a precipitation-hardenable nickel-chromium alloy. While casting is common for complex static parts, forging is mandatory for rotating or high-pressure components. Our forging process breaks down the cast dendritic structure and creates a directed grain flow, significantly increasing fatigue life and structural reliability.

The Mechanical Advantage

• Yield Strength: Retains 1,035 MPa at temperatures up to 700°C (1,292°F).
• Creep Resistance: Optimized for long-term stability under high-stress thermal loads.
• Workability: Excellent weldability and cryogenic properties compared to other nickel superalloys.

Technical Specifications & Standards

We forge Inconel 718 to comply with the most stringent global standards, ensuring seamless integration into Tier-1 aerospace and energy supply chains.

Industry Standards Compliance

• Aerospace: AMS 5662 (Solution Annealed), AMS 5663 (Precipitation Hardened)
• Oil & Gas: NACE MR0175 / ISO 15156
• General: ASTM B637, UNS N07718

Specialized Forging Processes for 718

• Closed-Die Forging: For high-precision, near-net-shape turbine disks and compressor blades.
• Seamless Rolled Rings: Ideal for engine casings and structural rings up to 3,500mm OD.
• Open-Die Forging: Cost-effective for shafts, custom blocks, and prototypes up to 5,000kg.

Quality Assurance & NDT Protocol

Every Inconel 718 forging undergoes rigorous testing at our co-owned facilities to ensure zero defects:

• Ultrasonic Testing (UT): Performed to AMS 2154 standards to identify internal inclusions or porosity.
• Fluorescent Penetrant Inspection (FPI): For surface crack detection in complex geometries.
• Macro-Etch Testing: To verify the integrity and directionality of the forged grain flow.
• Mechanical Verification: Tensile and creep testing on witness coupons from every heat lot.
