RAYCHIN LIMITED specializes in manufacturing high-performance Incoloy Fasteners designed to withstand extreme temperatures, corrosive environments, and high-stress applications. Our product range includes:

• Incoloy Bolts: High-strength fasteners for critical applications, including Incoloy 800 bolts, Incoloy 825 bolts, and Incoloy 925 bolts.

• Incoloy Screws: Precision-machined Incoloy socket head screws and Incoloy machine screws for secure fastening in aggressive environments.

• Incoloy Nuts: Durable Incoloy hex nuts and Incoloy lock nuts engineered to resist galling and corrosion.

• Incoloy Washers: Incoloy flat washers and Incoloy spring washers for even load distribution and vibration resistance.

• Incoloy Studs: Incoloy threaded studs and Incoloy double-ended studs for flanged connections in high-pressure systems.

• Incoloy Threaded Rods: Custom Incoloy threaded rods for structural and assembly applications.

Mechanical Properties

Incoloy fasteners exhibit exceptional mechanical performance, including:

• High-Temperature Strength: Retain tensile and yield strength at temperatures up to 1100°C (e.g., Incoloy 800HT).

• Corrosion Resistance: Excellent resistance to oxidizing and reducing acids, chlorides, and sulfur-containing environments.

• Creep and Rupture Resistance: Superior performance under prolonged exposure to high temperatures and stresses.

• Oxidation Resistance: Form a protective oxide layer to prevent scaling and degradation in extreme environments.

Applications

Incoloy fasteners are widely used in industries requiring reliability under extreme conditions:

• Chemical Processing: Reactors, heat exchangers, and piping systems handling corrosive media.

• Power Generation: Gas turbines, boilers, and nuclear power components.

• Oil & Gas: Downhole tools, wellhead equipment, and sour service applications.

• Aerospace: Engine components and exhaust systems exposed to high temperatures.

• Industrial Furnaces: Radiant tubes, burners, and heat treatment fixtures.

Key Selection Factors

When choosing Incoloy fasteners, consider the following:

1. Temperature and Environment: Verify operating temperatures and exposure to corrosive agents (e.g., acids, chlorides).

2. Mechanical Requirements: Ensure tensile strength, creep resistance, and fatigue life align with application demands.

3. Material Grade: Select the appropriate grade (e.g., Incoloy 825 for acidic environments, Incoloy 800HT for high-temperature stability).

4. Certifications: Ensure compliance with industry standards such as ASTM B409, ASTM B423, and NACE MR0175.

5. Design Specifications: Confirm thread type, dimensions, and surface treatments (e.g., passivation) for optimal performance.
