RAYCHIN LIMITED specializes in manufacturing high-performance Inconel 718 12-point screws, engineered to deliver exceptional strength and reliability in the most demanding applications. Our screws are crafted from nickel-chromium-based superalloy Inconel 718 (also known as NI-P100HT or NI-PH2601), which offers outstanding resistance to high temperatures, corrosion, and stress. 

Key features include:

· High-Temperature Performance: Maintains a classification of 1275 MPa at ambient temperature and 650°C , ensuring stability in extreme heat.

· Precision Design: The 12-point head (double hexagon) allows for secure torque application and reduced risk of stripping, ideal for aerospace and industrial use .

· Versatile Product Range: We supply a full range of Inconel 718 twelve-point screws, including bolts with relieved shanks, short-thread variants, and custom lengths and coatings (e.g., silver-plated for reduced friction ).

Product Categories:

1. Inconel 718 12-Point Bolts with Relieved Shank.

2. Inconel 718 12-Point Flange Head Bolts.

3. Inconel 718 12-Point Screws for Aerospace.

Applications Across Industries

Inconel 718 twelve-point screws are designed for critical applications where failure is not an option:

· Aerospace: Jet engine components (e.g., turbine blades, combustion chambers), airframe structures, and rocket assemblies.

· Oil & Gas: Wellhead equipment, offshore platforms, and high-pressure valves exposed to H₂S and seawater corrosion.

· Energy & Chemical Processing: Gas turbines, nuclear reactors, and reactors in acidic or chloride-rich environments.

· High-Temperature Vacuum Systems: Components for space telescopes and vacuum environments where low volatility and anti-galling properties are critical.

Key Selection Factors for Optimal Performance

When integrating Inconel 718 12-point screws, consider these factors to ensure safety and longevity:

1. Temperature and Load Requirements:

· Suitable for continuous service from cryogenic temperatures (-253°C) up to 650°C .

· Verify tensile strength (e.g., 1275 MPa at room temperature ) and anti-creep properties for sustained loads.

2. Corrosion and Oxidation Resistance:

· Resists pitting, stress corrosion cracking, and oxidation in acidic, saline, or high-humidity environments .

3. Dimensional and Standards Compliance:

· Ensure alignment with international standards (e.g., IFI115, AS, NAS, DIN EN 2927, EN 3388, or BS EN 4635 ).

4. Installation and Maintenance:

· Use anti-galling coatings (e.g., silver plating ) to prevent thread seizure during torque application.

· Adhere to controlled torque settings to avoid over-tightening and stress concentration.

5. Environmental Compatibility:

· For vacuum or extreme low-temperature applications, confirm low volatility and toughness via certifications like EN 10204 3.1 .
