Key Features:

Superior Corrosion and Oxidation Resistance:

• Excellent resistance to oxidation, carburization, and a wide range of corrosive environments, including seawater, chemicals, and acidic gases.
• Exceptional resistance to pitting and crevice corrosion in chloride environments.
• Forms a stable, protective oxide layer that provides resistance to oxidation at high temperatures (up to 980°C or 1800°F).

High-Temperature Strength:

• Excellent strength and stability at high temperatures, including resistance to creep and thermal fatigue.
• Retains high tensile, fatigue, and rupture strength even at elevated temperatures, making it ideal for high-temperature industrial applications.

Workability:

• Weldability: Inconel 625 has excellent weldability and can be welded using most standard processes, including TIG, MIG, and gas welding, without requiring preheating.
• It can be easily cold-formed and hot-worked, making it versatile for a variety of applications.

Niobium and Molybdenum:

• The alloy’s niobium content stabilizes the alloy, improving its strength and resistance to corrosion, particularly in environments that would degrade other materials.
• Molybdenum enhances its resistance to pitting and crevice corrosion in chloride-rich environments, such as seawater.

Fatigue and Thermal Fatigue Resistance:

• Outstanding resistance to both fatigue and thermal fatigue. This makes it particularly useful in cyclically loaded applications where high temperatures and aggressive environments are factors.

Applications:

• Chemical Processing: Used in chemical processing equipment, heat exchangers, and valves for its resistance to corrosive chemicals.
• Power Generation: Employed in gas turbines, steam turbines, and other components within the power generation industry.
• Aerospace Industry: Utilized in aircraft engines, exhaust systems, and other high-temperature components.
• Marine Applications: Suitable for marine environments due to its resistance to seawater corrosion.
