Frequently Asked Question About Inconel Fasteners

1. What are Inconel Fasteners, and why are they used in industrial applications?

Inconel fasteners are high-performance fasteners made from Inconel, a nickel-chromium-based superalloy known for its excellent corrosion resistance, high-temperature strength, and durability. They are widely used in aerospace, marine, chemical processing, and power generation industries due to their ability to withstand extreme environments such as high temperatures, oxidation, and pressure.

2. What are the common grades of Inconel Fasteners?

The most common grades of Inconel fasteners include:

• Inconel 625: High strength and excellent fatigue resistance, suitable for marine and chemical environments.
• Inconel 718: High tensile strength, stress-corrosion resistance, and used in aerospace applications.

3. What are the applications of Inconel Nuts and Bolts?

Inconel nuts and bolts fasteners are commonly used in:

• Gas turbines and jet engines
• Heat exchangers and chemical reactors
• Offshore oil and gas drilling platforms
• Nuclear power plants
• Exhaust systems and automotive turbochargers

4. How do Inconel Fasteners compare with stainless steel fasteners?

Inconel fasteners offer superior high-temperature resistance and corrosion resistance compared to stainless steel fasteners. While stainless steel is cost-effective for general applications, Inconel is preferred in extreme environments such as aerospace and chemical processing. Inconel retains its strength and integrity at temperatures exceeding 1000°C, whereas stainless steel may weaken.

5. What is the price range for Inconel Bolts in India?

The price of Inconel bolts in India varies based on the grade, size, and quantity. On average, it ranges between ?200 to ?500 per bolt, depending on specifications. Customizations and certifications like ASTM or ISO compliance can increase the cost.

6. Who are the top Inconel Fasteners manufacturers and suppliers in India?

Some leading manufacturers and suppliers in India include:

• Ananka Fasteners: Known for high-quality Inconel fasteners with global exports.

These companies provide custom solutions, fast delivery, and adherence to international standards.

7. What are the benefits of using Inconel Fasteners in marine applications?

Inconel fasteners provide exceptional resistance to saltwater corrosion, high durability in marine environments, and the ability to withstand extreme pressures and temperatures. This makes them ideal for offshore platforms, shipbuilding, and marine turbines.

8. How do I choose the right grade of Inconel Fasteners for my project?

To choose the right grade:

• Consider the operating temperature and pressure.
• Evaluate the chemical exposure (e.g., saltwater, acids).
• Review the mechanical strength requirements.
• Consult with manufacturers for guidance based on your specific application.

9. Are Inconel Fasteners suitable for high-temperature environments?

Yes, Inconel fasteners are specifically designed for high-temperature environments. They can maintain mechanical integrity and resist oxidation at temperatures above 1000°C, making them ideal for gas turbines, furnaces, and heat exchangers.

10. Can Inconel Fasteners be customized for specific applications?

Absolutely! Leading manufacturers like Ananka Fasteners provide custom Inconel fasteners tailored to specific requirements, including size, grade, threading, and coatings. Custom fasteners often come with certifications like ASTM, ASME, and ISO standards for quality assurance.
