Incoloy 925 is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium, designed for exceptional resistance to both oxidizing and reducing corrosive environments. It offers excellent mechanical properties, including high tensile and yield strength, good toughness, and stable performance over a wide temperature range. Incoloy 925 Forgings also provide superior resistance to pitting, crevice corrosion, and stress corrosion cracking, making them suitable for highly aggressive chemical and marine environments.

The ideal temperature range for forging Incoloy 925 is between 1,800°F (982°C) and 2,200°F (1,204°C). Forging should be done within this range to achieve optimal material properties and avoid overheating.
Incoloy 925 forgings require minimal maintenance due to their excellent corrosion resistance. Regular inspection for signs of wear, cracks, or environmental damage is recommended to ensure long-term performance.
Incoloy 925 forgings have limited high-temperature strength beyond 1,600°F (871°C) and may suffer from reduced ductility in extreme conditions. They also exhibit moderate resistance to pitting and crevice corrosion in highly aggressive environments.
Incoloy 925 Forgings are widely used in applications requiring high corrosion resistance, mechanical strength, and durability. They are commonly employed in chemical processing equipment, heat exchangers, pressure vessels, valves, and piping systems. The alloy is also used in marine, petrochemical, and power generation applications where resistance to strong acids, chlorides, and harsh environments is critical. Due to its combination of corrosion resistance, strength, and reliability, Incoloy 925 is ideal for demanding industrial and chemical applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
