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 find extensive use in industries that need exceptional strength and corrosion resistance, particularly in aggressive and high-pressure settings. They are perfect for components in the oil and gas industry, such as valves, tubing hangers, fasteners, subsurface safety devices, and marine hardware. Their outstanding resistance to sour-gas environments makes them ideal for downhole and offshore applications. Furthermore, Incoloy 925 is utilized in chemical processing, pollution-control systems, and power-generation equipment, where durability, stress-corrosion resistance, and mechanical stability are crucial for safe and efficient operations.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
