A-286 (UNS S66286) Iron-Based Superalloy Strip High-Strength Fasteners & Turbine Components

A-286 (UNS S66286) is a precipitation-hardened, iron-based superalloy known for its excellent high-temperature strength, corrosion resistance, and creep resistance. It is widely used in aerospace, gas turbines, and industrial applications where high mechanical performance under extreme conditions is required.

This alloy strip is particularly valued for manufacturing high-strength fasteners, turbine components, and exhaust systems, making it a critical material in advanced engineering.

Key Properties of A-286 Alloy Strip

A-286 offers a balanced combination of properties, including:

✔ High Tensile Strength – Maintains strength up to 1300°F (700°C).

✔ Excellent Creep Resistance – Performs well under prolonged stress at elevated temperatures.

✔ Good Oxidation & Corrosion Resistance – Resists scaling and degradation in harsh environments.

✔ Age-Hardenable – Can be strengthened through heat treatment (solution annealing + aging).

✔ Machinability & Weldability – Easier to process compared to nickel-based superalloys.

Typical Composition (wt%):

Iron (Fe): Balance

Nickel (Ni): 24-27%

Chromium (Cr): 13.5-16%

Molybdenum (Mo): 1.0-1.5%

Titanium (Ti): 1.9-2.35%

Aluminum (Al): ≤0.35%

Primary Applications of A-286 Alloy Strip

1. Aerospace Fasteners (Bolts, Screws, Nuts)

A-286 is a preferred material for high-strength fasteners in jet engines and airframes due to its:

High shear and tensile strength (up to 160 ksi / 1100 MPa after aging).

Reliable performance under thermal cycling (e.g., engine mounts, structural joints).

2. Turbine & Jet Engine Components

Turbine blades, discs, and casings – Where creep resistance is critical.

Afterburner parts & exhaust systems – Due to oxidation resistance at high temps.

3. Industrial Gas Turbines & Power Generation

Combustor liners, bolts, and washers – Withstanding extreme heat and pressure.

High-temperature valves & pumps – Used in chemical and petrochemical industries.

4. Automotive & Racing Exhaust Systems

Turbocharger components – Where thermal fatigue resistance is needed.

High-performance exhaust manifolds – Reducing weight while maintaining durability.

Why Do Customers Choose A-286 Alloy Strip?

✔ Cost-Effective Alternative to Nickel-Based Superalloys

A-286 provides similar high-temperature performance to Inconel 718 but at a lower cost, making it ideal for budget-sensitive projects.
