CNC machined Inconel 718 AMS 5662 part

Description

1. Product Overview
This listing offers precision CNC-machined components manufactured from Inconel 718 AMS 5662, a precipitation-hardened nickel-chromium superalloy engineered for extreme service conditions. These parts are primarily used in high-temperature, high-corrosion environments such as aerospace turbine sections, oil & gas downhole tools, and power generation gas turbines. The key value proposition is exceptional creep resistance and tensile strength up to 1300°F (705°C), combined with outstanding post-machining dimensional stability. Strategically, securing a reliable source of AMS 5662 machined parts mitigates supply chain risk for mission-critical rotating and static components, directly impacting operational uptime and lifecycle cost reduction.

2. Key Specifications & Technical Characteristics

• Material Composition (AMS 5662 compliant): Nickel (50-55%), Chromium (17-21%), Iron (balance), Niobium (4.75-5.5%), Molybdenum (2.8-3.3%), Titanium (0.65-1.15%), Aluminum (0.2-0.8%)

• Purity / Grade: Aerospace-grade, solution heat-treated + precipitation hardened (condition: aged to AMS 5663 standard tensile properties)

• Physical Characteristics: Machined to customer drawing tolerances (standard ±0.005 in, achievable ±0.0005 in); surface finish as-machined (32 μin Ra) or better per spec; passivated for oxidation resistance

• Density: 8.19 g/cm³ (0.296 lb/in³)

• Hardness: 35–42 HRC (aged condition)

• Packaging Options: VCI-coated individual polybags + foam-lined anti-static trays; bulk wooden crates (ISTA 3B certified) for larger quantities; vacuum-sealed moisture barrier available for long-term storage

• Shelf Life: Indefinite when stored in dry, climate-controlled environment (below 50% RH, no corrosive atmosphere)

3. Core Industrial Applications

• Primary Industries: Aerospace & Defense (turbine engines, exhaust systems), Oil & Gas (subsea wellhead components, completion tools), Power Generation (gas turbine blades, nuclear reactor internals), Automotive Motorsport (turbocharger rotors, exhaust manifolds)

• Specific Use Cases: High-pressure pump shafts, turbine discs, fastener hardware (bolts/nuts) exposed to sour gas (H₂S), cryogenic down to -320°F, and cyclic thermal loads

• Performance Advantage: Unlike 17-4PH or 304 stainless, Inconel 718 retains >90% of room-temperature yield strength at 1200°F. Compared to cast equivalents, CNC machined from wrought bar eliminates porosity and provides consistent grain flow – reducing field failure rates by an estimated 40-60% in cyclic fatigue applications

• Cost Advantage: Lower total cost of ownership (TCO) due to extended mean time between overhauls (MTBO) – documented 3x longer service intervals in corrosive wellbore environments vs. duplex stainless

4. Competitive Advantages

• Quality Consistency: Lot traceability to ASTM E1479; each part includes a certificate of conformance (CoC) with actual chemistry and mechanical test results; statistical process control (SPC) data available upon request

• Supply Reliability: Stock of AMS 5662 bar stock (Ø0.5” to 8”) in a US-based bonded warehouse – typical lead time 10 working days for custom CNC machined parts; no upstream smelter single-point failure

• Logistics Capability: Door-to-door delivery to 45 countries via Tier-1 freight partners; export crating compliant with ISPM-15 for wood packaging

• Price Competitiveness: Direct mill-to-shop pricing eliminates 2–3 intermediary margins – typically 18-22% below distributor-supplied equivalent parts on annual blanket orders >50 pieces

• Technical Support: In-house metallurgist and applications engineering team provides failure analysis, reverse engineering, and CAD-to-part conversion within 48 hours

• Sustainability: 100% recyclable material; machining chips returned via closed-loop scrap buyback program (up to 15% credit on next purchase)

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 10 pieces per unique part number (for standard tolerances); 50 pieces for custom geometries

• Bulk Loading Capacity (20 MT / 20FT container): Approx. 3,500 kg net weight per palletized configuration (dependent on part geometry – typical 20MT container holds 6,000–9,000 individual small-to-medium parts)

• Standard Pack Quantity: Supplied in sealed anti-static bags at 50–200 pieces per inner box (based on weight not exceeding 5 kg per box)

• Payment Terms: Net 30 days (approved corporate accounts); Letter of Credit (L/C at sight) for first-time buyers; credit cards via platform for samples under $5,000

• Lead Time for Samples: 5 business days (3 pieces max) – expedite available at +25%
