Aung Metals, a well-respected manufacturer and supplier located in Naypyidaw, Myanmar, is known for its top-notch Incoloy 925 Forgings. These forgings blend the robust qualities of a nickel-iron-chromium base with the impressive corrosion resistance provided by molybdenum, copper, and titanium. Tailored for high-performance applications, Incoloy 925 Forgings excel in resisting stress-corrosion cracking, pitting, and crevice corrosion, whether in oxidizing or reducing environments. Aung Metals prides itself on precision engineering, ensuring dimensional accuracy and strict compliance with international quality standards, making these forgings perfect for challenging marine, chemical, and oil & gas applications.
Incoloy 925 Forgings consist of about 38–46% nickel, 19.5–23.5% chromium, 2.5–3.5% molybdenum, 1.5–3% copper, 0.2–0.5% titanium, with the remainder being iron. This unique composition strikes an excellent balance between strength, corrosion resistance, and thermal stability. On the mechanical side, these forgings boast a tensile strength of around 760 MPa and a yield strength of 414 MPa, maintaining high ductility and toughness even in extreme temperatures and harsh conditions. Their makeup ensures outstanding resistance to chloride-induced corrosion and sulfide stress cracking.

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 their place in industries where strength and corrosion resistance are paramount. They are particularly suited for creating components in oil and gas extraction, marine engineering, chemical processing, and power generation. Common uses include valve parts, fasteners, shafts, hangers, and tubular products that come into contact with aggressive media. Their ability to endure high pressures, temperatures, and corrosive fluids makes them ideal for sour gas wells and offshore settings. Incoloy 925 Forgings deliver long-lasting reliability, durability, and performance in even the most demanding industrial operations.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
