Inconel 718 bolt AMS 5662

Description

Product Overview
Inconel 718 bolt (AMS 5662) — a high-strength, precipitation-hardenable nickel‑chromium‑iron superalloy fastener manufactured to AMS 5662 standards. Engineered for extreme environments, these bolts deliver exceptional tensile and creep-rupture strength at temperatures up to ~700°C, plus superior corrosion and oxidation resistance. Primary uses include critical fastening in aerospace engines, gas turbines, power generation, and high-performance industrial equipment where safety and reliability are non‑negotiable. Strategically, AMS‑specified Inconel 718 bolts reduce lifecycle risk, enable higher operating temperatures, and simplify inventory consolidation for quality-driven OEMs and MRO providers.

Key Specifications & Technical Characteristics

• Material: Inconel 718 (Nickel‑Chromium‑Iron superalloy), conforms to AMS 5662.

• Chemical composition (typical ranges): Nickel (Ni) ~50–55%, Chromium (Cr) ~17–21%, Iron (Fe) balance, Niobium + Tantalum (Nb+Ta) ~4.75–5.5%, Molybdenum (Mo) ~2.8–3.3%, Titanium (Ti) ~0.65–1.15%, Aluminum (Al) ~0.2–0.8%; trace C, Mn, Si, S per AMS spec.

• Mechanical properties: High tensile strength and yield strength after precipitation hardening; excellent creep-rupture resistance to ~700°C (specific values per size and heat treatment to be provided on request).

• Heat treatment: Solution treated and precipitation hardened per AMS/ manufacturer process to meet AMS 5662 mechanical property tables.

• Physical characteristics: Metallic, silvery‑gray finish; form: machined bolt (threaded to specified class), available in standard imperial and metric diameters and lengths per engineering drawing.

• Thread & head specifications: Delivered to customer drawing or standard aerospace threads (UNJ/UNF/UNC) and head styles per AMS/engineering requirements.

• Tolerances & testing: Manufactured to aerospace tolerances; supplied with chemical analysis, mechanical test reports, hardness, and dimensional inspection certificates per AMS requirements.

• Corrosion resistance: Superior resistance to oxidation and corrosion in high-temperature and corrosive atmospheres.

• Packaging options: Industrial bulk crates, wooden pallets, sealed metal or poly coils for small quantities; custom protective packaging (wax coating, desiccant, vacuum wrap) available for long-term storage or export shipments.

• Shelf life: Indefinite under proper storage (dry, controlled environment); recommended re-inspection after prolonged storage (>5 years) if required by purchaser quality program.

• Traceability: Full heat lot traceability, Certificate of Conformance (CoC), and material test reports (MTRs) included.

Core Industrial Applications

• Aerospace & Defense: Engine and airframe critical fasteners — turbine casings, combustor assemblies, and high‑temperature structural joints where failure is catastrophic. Outperforms conventional stainless steels by retaining strength and resisting creep at elevated temperatures.

• Power Generation: Gas turbines and steam turbines — rotor and casing bolting, hot-section fasteners that require long-term creep resistance and oxidation stability.

• Oil & Gas / Petrochemical: High‑temperature valves, flanges, and pilot assemblies exposed to corrosive and high‑pressure conditions; preferred where sulfide stress cracking and high‑temp corrosion are concerns.

• Industrial Manufacturing & Metallurgy: High‑temperature tooling, heat-treatment fixtures, and critical assemblies in furnaces or processing lines that demand dimensional stability and fatigue resistance.
  Why it performs better than alternatives

• Retains tensile and yield strength at temperatures far above typical stainless steels, reducing maintenance and downtime.

• Exceptional creep and fatigue resistance extends service intervals and improves safety margins.

• Industry‑standard AMS 5662 specification ensures predictable, audit‑friendly performance for regulated OEMs and MROs.
  Efficiency, durability, cost advantages

• Longer in-service life decreases replacement frequency and total cost of ownership.

• Consolidation to a single high-performance alloy reduces inventory complexity for critical spares.

• Predictable mechanical behavior under thermal cycling reduces risk and engineering contingencies.

Competitive Advantages

• Quality consistency: Manufactured and inspected to AMS 5662 with full MTRs, dimensional checks, and certificate of conformance for every lot.
