Inconel 718 Casting Key Facts: Inconel 718 (UNS N07718 / AMS 5383) is a high-strength, corrosion-resistant nickel superalloy investment cast using Vacuum Induction Melting (VIM) and 100% Hot Isostatic Pressing (HIP) to eliminate porosity. Engineered for extreme thermal and high-stress environments up to 704°C (1,300°F), ForceBeyond’s AS9100-certified facilities provide complete precision 5-axis CNC machining, solution heat treatment, and NDT inspection for aerospace turbines, rocket engine components, and nuclear SMR applications.
ForceBeyond is a specialized Inconel 718 casting supplier providing mission-critical components for aerospace, space exploration, and power generation. Through our co-owned foundry network in the USA, South Korea, and Taiwan, we deliver high-strength, corrosion-resistant Inconel 718 parts utilizing advanced Vacuum Induction Melting (VIM) technology. Our dual-shore model combines domestic engineering expertise with global manufacturing scale to ensure quality and supply chain redundancy. The sizes of the casting parts range up to 32 inches. The weights of the vacuum casting parts are from 0.02 to 220 pounds. Typical casting tolerances meet ISO 8062 CT7 to CT5/ VDG P690 D1 to D2. As part of our broader Superalloy Casting a expertise, we utilize Hot Isostatic Pressing (HIP) to eliminate internal microporosity, ensuring our 718 parts meet the rigorous AS9100 standards required for mission-critical energy infrastructure.
ForceBeyond ensures all Inconel 718 castings meet rigorous international standards, including AMS 5383 and ASTM B637. We provide full material traceability (MTRs) and NDT reports with every shipment to verify mechanical integrity.
| Alloy Grade | Value (Typical Cast & Aged) |
|---|---|
| Tensile strength | 125,000 psi (860 MPa) |
| Yield strength(0.2% offset) | 110,000 psi (760 MPa) |
| Elongation | 5% – 10% |
| Service Temperature | Up to 1300°F (704°C) |
A stable supply of Inconel 718 requires more than just a vendor; it requires a manufacturing partner with direct oversight.
Hot Isostatic Pressing (HIP) for Zero-Defect Castings
To meet the fatigue-life requirements of rotating engine components, ForceBeyond utilizes Hot Isostatic Pressing (HIP) for all critical Inconel 718 castings. By subjecting the parts to 15,000+ psi at high temperatures, we effectively “heal” any internal microporosity common in nickel-alloy castings. This process results in a part with mechanical properties that rival forged components, making them suitable for the most demanding high-stress environments.
ForceBeyond provides a seamless transition from Vacuum Investment Casting to finished print dimensions. Because Inconel 718 is exceptionally hard to machine (up to 44 HRC after aging), our Tier-1.5 model integrates our casting foundries with our specialized Inconel 718 Machining centers.
By managing both casting and 5-axis CNC machining under one AS9100 quality umbrella, we eliminate the dimensional “hand-off” risk. We provide Proof Machining on as-cast surfaces to facilitate more accurate NDT (Ultrasonic Testing) and ensure that critical datum features are perfectly aligned for final finish machining.
