Key Features:
Nickel (Ni): 58%–70% (balance of the alloy).
Chromium (Cr): 20%–23% (providing resistance to oxidation and corrosion).
Molybdenum (Mo): 8%–10% (adds resistance to pitting, crevice, and stress corrosion
cracking).
Iron (Fe): 5%–10%.
Other elements include niobium (Nb), titanium (Ti), and small
amounts of carbon, manganese, and silicon.
Tensile Strength: Approx. 1,380–1,500 MPa (varies depending on the form and
temperature).
Yield Strength: Approx. 690–800 MPa.
Elongation: Typically around 30% (providing good ductility).
Hardness: Good hardness properties, typically in the range of Rockwell B
90–95.
- Corrosion and Oxidation Resistance:
Excellent Resistance to a wide range of aggressive environments, including sea water,
acidic solutions, and high-temperature gases.
Inconel 625 has superior resistance to pitting, crevice corrosion, and stress
corrosion cracking, making it ideal for use in severe service conditions.
Performs well in oxidizing and reducing environments due to its
high chromium and molybdenum content.
It is particularly resistant to high-temperature oxidation and to
carburization, making it ideal for high-temperature applications in
combustion and furnace environments.
Melting Point: Around 1,350°C–1,400°C (2,462°F–2,552°F).
Thermal Conductivity: Lower than pure metals like copper, but adequate for
high-temperature applications.
Coefficient of Expansion: Moderate, making it stable under thermal cycling.
- Electrical and Magnetic Properties:
Electrical Conductivity: Relatively low compared to copper, typical for high-performance
alloys.
Magnetic Permeability: Inconel 625 is non-magnetic, making it suitable for sensitive
electronic or magnetic applications.
- Weldability and Fabrication:
Excellent Weldability: Inconel 625 has good weldability by most standard welding
methods, including TIG, MIG, and plasma welding. It can be welded
in both the annealed and solution-treated conditions.
Can be cold-formed and hot-formed, though hot forming must be done with caution to avoid excessive
grain growth.
Machinability: Although it is a tough material, it can be machined, albeit with
difficulty. It is generally recommended to use carbide tools for
machining.
Applications:
- Aerospace: Used in turbine blades, seals, exhaust systems, and other
high-temperature engine components due to its heat and corrosion
resistance.
- Chemical Processing: Equipment exposed to high-temperature and corrosive chemicals,
such as heat exchangers, reactors, and piping systems.
- Marine Environments: Due to its outstanding resistance to seawater corrosion, Inconel
625 is used in marine and offshore applications, such as subsea
equipment, propeller blades, and other parts exposed to saltwater.
- Nuclear Power: Used in reactor cores, steam generator tubing, and other parts
exposed to radiation and high temperatures.
- Oil and Gas: Ideal for high-performance applications like gas turbines,
deep-sea equipment, and equipment exposed to extreme pressure and
temperature conditions.
- Industrial Furnace: For parts like furnace linings, heating elements, and combustion
chambers.
