Key Features:

• Excellent Corrosion Resistance:

Outstanding resistance to a wide range of aggressive environments, including seawater, acids (sulfuric, phosphoric, and nitric), alkalis, and gases.

Exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, making it ideal for harsh chemical and marine environments.

Excellent resistance to oxidation and carburization, maintaining performance even at elevated temperatures (up to 980°C or 1800°F).

• High-Temperature Performance:

Inconel 625 retains high strength and toughness at elevated temperatures, with good resistance to thermal-fatigue, oxidation, and corrosion.

The alloy forms a stable oxide layer that enhances its performance at high temperatures and prevents further degradation.

• Mechanical Properties:

High tensile strength, fatigue, and creep resistance at elevated temperatures.

Good resistance to thermal expansion and contraction, which makes it suitable for applications where rapid temperature fluctuations occur.

• Workability:

Good weldability, often used in welding and joining processes, including gas tungsten arc welding (TIG), gas metal arc welding (MIG), and submerged arc welding (SAW).

Easily fabricated into wire, sheet, plate, tube, and other forms for a variety of industrial applications.

Can be used in cryogenic temperatures as well as elevated-temperature environments, offering versatility across a wide temperature range.

• Niobium and Molybdenum:

The inclusion of niobium and molybdenum provides significant resistance to grain boundary precipitation, improving the alloy's toughness and strength at high temperatures.

Molybdenum further enhances the alloy's resistance to crevice corrosion, pitting, and general corrosion.
