Semih Metals, based in Istanbul, Turkey, has made a name for itself as a top manufacturer and supplier of high-quality Incoloy 925 Forgings, serving clients around the globe. With a strong focus on excellence and precision engineering, the company guarantees that its products adhere to strict international standards, ensuring they deliver outstanding strength, reliability, and durability. Incoloy 925 Forgings are particularly prized for their remarkable resistance to corrosion, oxidation, and stress cracking, making them ideal for tough environments like marine and oilfield operations. Committed to customer satisfaction, timely deliveries, and competitive pricing, Semih Metals has established itself as a trusted partner for advanced nickel-iron-chromium alloy forging solutions worldwide.
Incoloy 925 Forgings are crafted from nickel-iron-chromium alloys, enhanced with molybdenum, copper, and titanium to offer exceptional corrosion resistance and high strength. This alloy stands up well against both reducing and oxidizing environments, as well as stress-corrosion cracking and pitting in chloride conditions. Typically, these forgings boast a tensile strength of around 760 MPa and a yield strength of about 450 MPa, ensuring they perform reliably under demanding service conditions. With impressive toughness, fatigue resistance, and weldability, Incoloy 925 maintains its structural integrity even in aggressive environments. Its unique blend of mechanical properties and chemical stability makes it the go-to material for high-stress, corrosion-prone applications in critical industries.

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 various industries that need materials capable of performing reliably under corrosive and high-pressure conditions. They are widely used in oil and gas production for downhole equipment, valves, tubular components, and fasteners, where resistance to sour-gas environments is crucial. In the marine sector, they are utilized in shafts, fittings, and seawater processing equipment. The chemical and petrochemical industries also rely on them for heat exchangers, pumps, and reactors that are exposed to harsh chemicals.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
