When it comes to Incoloy 925 Forgings, Rupal Metals stands out as a trusted manufacturer and supplier based in Delhi, India. This high-performance nickel-based alloy is renowned for its exceptional resistance to corrosion, pitting, and stress-corrosion cracking, especially in tough environments like sour gas and offshore oil fields. Rupal Metals specializes in precision-engineered forgings that adhere to strict international standards and cater to specific customer needs. With cutting-edge forging capabilities and a strong commitment to quality, Rupal Metals supports a variety of industries, including oil & gas, marine, power generation, and chemical processing, where durability and corrosion resistance are crucial.
Incoloy 925 (UNS N09925) is a robust nickel-iron-chromium alloy that consists of nickel (42–46%), iron (at least 22%), chromium (19.5–23.5%), along with molybdenum, copper, titanium, and aluminum. This alloy undergoes heat treatment to achieve impressive strength through precipitation hardening. It boasts excellent tensile strength (typically over 760 MPa), good ductility, and remarkable resistance to sulfide stress cracking, chloride-induced pitting, and crevice corrosion. Incoloy 925 performs exceptionally well under extreme pressure and temperature conditions, making it perfect for harsh chemical and marine environments. Plus, it offers great weldability and structural integrity even in demanding service conditions.

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.
Rupal Metals’ Incoloy 925 Forgings are extensively utilized in oil & gas exploration, marine engineering, and chemical processing, thanks to their outstanding resistance to acidic, chloride-rich, and high-pressure environments. You’ll find them in various applications, including downhole tubing, valves, hangers, connectors, subsurface safety valves, and pump shafts. Their strength and durability make them a top choice for industries that require reliable performance in challenging conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
