Semih Metals, based in Istanbul, Turkey, has established itself as a reliable manufacturer and supplier of Incoloy 800 forgings, crafted for exceptional performance in high-temperature and corrosive settings. Renowned for their precision-engineered components, Semih Metals caters to critical industries that require dependable and long-lasting forged materials. With a strong commitment to quality assurance and cutting-edge production methods, the company guarantees that its Incoloy 800 forgings not only meet but often surpass global industry standards, supporting applications in fields like petrochemical processing, power generation, and industrial heating systems.
The composition of Incoloy 800 forgings primarily includes nickel (30–35%), iron (at least 39.5%), and chromium (19–23%), along with carefully controlled amounts of aluminum and titanium to enhance strength and oxidation resistance. This alloy is particularly recognized for its stability and structural integrity at elevated temperatures. It boasts impressive mechanical properties, such as a tensile strength of around 600 MPa, a yield strength of about 275 MPa, and an elongation of approximately 30–45%. These characteristics enable Incoloy 800 to maintain its strength and resist carburization, oxidation, and stress-related corrosion cracking, even after extended exposure to high heat.

Yes, Incoloy 800 can be forged into custom shapes. Its excellent high-temperature resistance and strength make it suitable for various forging processes.
The ideal temperature range for forging Incoloy 800 is between 1,800°F to 2,200°F (982°C to 1,204°C). This range ensures optimal ductility and workability during the forging process.
To assess the forging strength of Incoloy 800 for aerospace applications, evaluate its tensile strength, yield strength, and fatigue resistance at elevated temperatures. Additionally, assess its performance under cyclic loads and long-term thermal stability.
Incoloy 800 forgings find their place in various applications, including heat exchangers, furnace components, superheater tubes, reformer outlet manifolds, and equipment used in chemical plants. Their ability to retain strength and resist scaling in high-temperature environments makes them particularly suited for thermal processing industries. They are especially beneficial in scenarios involving exposure to acids, combustion gases, and high-pressure steam. The combination of mechanical reliability and corrosion resistance ensures that Incoloy 800 forgings deliver effective performance over long operational lifespans, even in demanding conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
