Nickel Alloy High Temperature Bolt CNC Machining China Precision CNC Machining Service Custom High Temp Fastener

Nickel alloy high-temperature bolts are precision-engineered fasteners designed for extreme thermal environments, utilizing materials such as GH4080A and INCONEL 718. Through optimized thermal processing and precision CNC machining, these bolts maintain exceptional mechanical reliability under prolonged exposure to 600°C–750°C. They are widely adopted in aerospace, automotive engines, and power generation equipment where high-temperature integrity is critical.

1. Superior High-Temperature Performance: Capable of operating continuously at 650°C–730°C while retaining high tensile and creep resistance. Solution strengthening and aging heat treatments yield optimized microstructures (γ' phase + carbides) for sustained high-temperature strength.
2. Excellent Corrosion Resistance: The nickel-chromium austenitic matrix provides outstanding oxidation and hot corrosion resistance in aggressive environments.
3. Precision Manufacturing: Warm thread rolling at 300°C–400°C ensures rounded root and crest profiles, minimizing stress concentration. The rolling process preserves metal flow lines, enhancing fatigue life.
4. Rigorous Quality Control: Flow line inspection and defect screening (cracks/folds) ensure compliance with aerospace standards like EN 3326.

• Aerospace: Engine fastening systems, turbine components per EN 3326/EN 2935, sustaining shear loads at 650°C.
• Automotive: Turbocharger assembly bolts for high-temperature zones in engines.
• Power Generation: Steam turbine bolts in supercritical units, resisting creep-fatigue interaction.
• High-Temperature Chemical Equipment: Reactors and pipeline connections leveraging nickel alloy corrosion resistance.

We offer end-to-end customization:

• Material Selection Guidance: Alloy recommendation (e.g., INCONEL 718 or Waspaloy) based on temperature (600°C–1000°C) and corrosion requirements.
• Thread and Dimension Tailoring: MJ/UNJ thread profiles with rounded crests to optimize coating uniformity.
• Heat Treatment Optimization: Recovery heat treatment to address post-service hardness exceedance, improving toughness (impact energy up by 68%).
• Surface Treatment Options: MoS₂ lubrication or silver plating for optimized torque-tension relationships.

• Technical Consultation: Bolt selection and installation guidance per aerospace standards (e.g., EN 2583).
• Quality Assurance: Flow line analysis and high-temperature endurance testing per GB/T 14994 and ASME SB637.
• After-Sales Support: Installation guidance and maintenance recommendations to extend service life in high-temperature applications.
