Application fields of Inconel fasteners-bolts, nuts, screws, washers

Inconel 718, as a nickel-based high-temperature alloy, is widely used in the manufacture of fasteners that require extreme environmental tolerance due to its high strength, corrosion resistance, high-temperature stability and good processing performance. According to the search results, the customer groups of its fasteners are mainly concentrated in the following fields:

1. Aerospace and aero-engine manufacturing industry

- Inconel 718 is the main material for key components of aero-engines (such as turbine discs, blades, combustion chambers, fasteners, etc.). Its high-temperature performance and fatigue resistance make it the preferred material for aero-engine manufacturers such as GE and P&W. For example, 57% of the total weight of nickel-based alloys in the PW4000 engine is Inconel 718.

- Customer groups include: military and civil aircraft manufacturers, aero-engine parts suppliers, spacecraft structural parts manufacturers, etc.

2. Oil, gas and energy industry

- In oil drilling equipment, submarine pipelines, high-pressure and high-temperature environments, Inconel 718 fasteners are used to resist corrosive media (such as hydrogen sulfide, chloride) and high-pressure environments, and are commonly found in drilling platforms, valves, pump bodies and other equipment.

- Main customers: oil drilling companies, energy equipment manufacturers, deep-sea engineering contractors.

3. Nuclear industry and nuclear energy facilities

- The radiation resistance and high-temperature stability of Inconel 718 make it suitable for fasteners in nuclear reactor components (such as cooling systems, control rod brackets) and nuclear waste treatment equipment to ensure long-term safe operation.

- Customer groups: nuclear power plant operators, nuclear reactor design companies, nuclear fuel processing companies.

4. Chemical and metallurgical equipment manufacturing

- In the chemical industry, Inconel 718 fasteners are used in acid-resistant, alkali-resistant and high-temperature reaction vessels, heat exchangers, pipeline connections and other scenarios, such as sulfuric acid production equipment and chlor-alkali industrial equipment.

- Customers include: chemical plants, metallurgical equipment manufacturers, and special material processing companies.

5. High-end equipment and special machinery

- Industrial machinery (such as gas turbines, boilers, high-temperature furnaces) involving high-temperature and high-pressure environments, as well as large engineering structures such as ships, railways, and bridges, need to use Inconel 718 fasteners to ensure durability.

- Typical customers: heavy machinery manufacturers, shipbuilding companies, rail transit equipment suppliers.

6. Military and defense fields

- Inconel 718's high temperature resistance and impact resistance make it widely used in military equipment such as missiles, ships, and armored vehicles, especially connecting parts that require extreme environmental tolerance.

- Customer groups: defense contractors, military equipment research and development institutions.

7. New energy and power equipment

- In the fields of gas turbine power generation and geothermal energy development, Inconel 718 fasteners are used to fix high-temperature components, such as turbine blade connection bolts and high-temperature pipe flanges.

Summary

The customer groups of Inconel 718 fasteners are mainly high-value-added and high-reliability demand industries, covering aerospace, energy, chemical industry, military industry and other fields. Its core competitive advantage lies in the balance of high temperature strength, corrosion resistance and processing performance, meeting the long-term stability requirements in extreme environments.
