Product Overview: Precision-Engineered A286 Screws

At RAYCHIN LIMITED, we specialize in manufacturing A286 screws crafted from premium iron-nickel-chromium superalloys (e.g., UNS S66286/Incoloy A-286). Renowned for their exceptional high-temperature strength (up to 704°C/1300°F) and corrosion resistance, our screws are ideal for critical applications where reliability is non-negotiable.

Our A286 Screws Portfolio Includes:

1. A286 MJ Thread Pan Head Screws: Designed for aerospace standards (e.g., HB 7449), these screws combine high tensile strength (1100 MPa) with vibration resistance.

2. A286 Hex Bolts & Internal Wrenching Screws: Perfect for heavy-duty assemblies in corrosive environments, such as chemical processing equipment.

3. A286 Self-Locking/Torque Screws: Feature optimized thread designs for anti-loosening under dynamic loads.

4. Custom A286 Screws: Tailored dimensions, heads (pan, flat, hex), and coatings to meet specific OEM requirements.

Key Applications: Where Performance Matters

Our A286 screws excel in industries demanding resilience under extreme conditions:

· Aerospace: Turbine blades, engine mounts, and airframe assemblies (compliant with AMS 5731/5732 standards).

· Oil & Gas: Wellhead equipment, manifolds, and offshore platforms exposed to seawater and H₂S.

· Automotive & Racing: Turbochargers, exhaust systems, and high-stress components.

· Energy & Chemical Processing: Reactors, heat exchangers, and valves in acidic/oxidizing environments.

· Marine Engineering: Non-magnetic components and saltwater-resistant structures.

Critical Factors for Application Success

When selecting A286 screws, consider these factors to ensure optimal performance:

1. Temperature Limits: Maintain strength up to 704°C continuously; avoid prolonged exposure beyond 982°C to prevent oxidation.

2. Corrosion Compatibility: Resist pitting in chlorides and acids but verify suitability for specific media (e.g., sulfuric acid).

3. Stress & Load Requirements: High tensile strength (≥930 MPa) and creep resistance under sustained loads.

4. Thermal Expansion Management: Match coefficients with joined materials to prevent loosening in cyclic thermal cycles.

5. Installation Practices: Use controlled torque and anti-galling lubricants to avoid thread seizure.
