Inconel 718 Casting Key Facts: Inconel 718 (UNS N07718) is a precipitation-hardenable nickel-based superalloy that may be investment cast to applicable specifications such as AMS 5383. ForceBeyond supports vacuum investment casting using VIM for applicable routes, HIP where required, heat treatment, NDT, and precision 5-axis CNC machining. Published elevated-temperature property data extend to approximately 1300°F (704°C), while actual allowable service conditions depend on material condition, geometry, loading, environment, qualification requirements, and the governing specification.
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 manufacturing model combines US-based engineering support with production capacity across the network to improve supply-chain resilience. The current capability statement includes casting sizes up to 32 inches, weights from 0.02 to 220 pounds, and typical casting tolerances from ISO 8062 CT7 to CT5 / VDG P690 D1 to D2, subject to geometry and process review. As part of our broader Superalloy Casting Services expertise, HIP may be applied when required to reduce internal microporosity. Final acceptance is controlled by the applicable drawing, material specification, inspection plan, qualification requirements, and customer requirements.
ForceBeyond supports Inconel 718 investment casting programs to applicable material specifications such as AMS 5383. The governing specification, revision, heat-treatment condition, mechanical-property requirements, and inspection criteria are controlled by the customer drawing and purchase order. 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% |
| Elevated-temperature reference | Published property data extend to approximately 1300°F (704°C); allowable service conditions are application- and specification-dependent. |
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 Internal Porosity Control
Hot Isostatic Pressing (HIP) may be applied when required by the drawing, material specification, qualification plan, customer requirements, or service conditions. HIP can reduce internal microporosity and increase density, but it does not create a universal zero-defect condition or make cast and forged material interchangeable. Final fatigue and structural performance remain dependent on material condition, casting quality, heat treatment, geometry, surface condition, defects, inspection acceptance criteria, and service environment.
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 coordinating casting, heat treatment, inspection, and 5-axis CNC machining within one sourcing program, ForceBeyond can reduce avoidable dimensional hand-off risk. Proof machining and inspection planning may be used where appropriate to establish datum features and support downstream NDT or finish machining. Facility certifications and final acceptance requirements are confirmed for the selected production route and customer program.

Documentation and inspection are provided according to the applicable drawing, purchase order, material specification, qualification plan, and customer requirements. Where AMS 5383 is invoked, the applicable revision and acceptance requirements control.
| Inspection Method | Purpose for Inconel 718 Casting | Standard Compliance |
|---|---|---|
| Radiographic Testing (RT) | X-ray inspection to detect internal shrinkage or inclusions. | ASTM E192 / ASTM E1030 |
| Fluorescent Penetrant (FPI) | Identifying surface-breaking porosity or cracks. | ASTM E1417 or applicable customer requirement |
| Spectrographic Analysis | Verifying chemical balance (Ni, Cr, Fe, Nb, Mo, Ti, Al). | ASTM E1476 |
| Mechanical Testing | Room temperature and elevated temperature tensile testing. | ASTM E8 / ASTM E21 |
ForceBeyond is a premier Inconel 718 casting supplier headquartered in Delaware, USA. We offer a unique dual-shore advantage with co-owned foundries in the United States, South Korea, and Taiwan, providing direct control over quality and global supply chain redundancy.
Vacuum Induction Melting (VIM) is critical for Inconel 718 because it removes dissolved gases and prevents the formation of oxides. This results in a cleaner alloy with the high-stress durability required for aerospace engine parts.
