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 chemical processing, seawater handling, and the oil and gas industries, where resistance to chlorides, acids, and other corrosive substances is crucial. They are particularly well-suited for valves, pumps, heat exchangers, and piping systems that face harsh environments. This alloy is also utilized in marine equipment, desalination plants, and chemical reactors, offering reliable performance under high stress and corrosive conditions. Phehlukwayo Metal’s Incoloy 925 Forgings are highly regarded for their dependability in safety-critical components, ensuring that they meet the rigorous demands of various applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
