Aiman Metals of Kuala Lumpur, Malaysia, is a reliable supplier and manufacturer of high-quality Incoloy 800H Forgings that are engineered to meet high-end performance in hostile environments of high temperatures and corrosion. Popular for their superior resistance to carburization, oxidation, and thermal creep, these forgings are crafted to perform exceptionally well under severe service conditions. At Aiman Metals, we have expertise in custom solutions that guarantee precision, reliability, and maximum output for demanding industrial applications. Supported by sophisticated manufacturing processes and rigorous quality assurance, we have received the trust of customers in power generation, petrochemical, and heat treatment fields, providing long-term stability and reliable performance.
Incoloy 800H Forgings consist mainly of Nickel (30–35%), Chromium (19–23%), and Iron (balance), along with minute but useful additions of Aluminum and Titanium to provide increased strength and stability. These forgings possess high yield and tensile strength, superior resistance to oxidation and carburization, and higher creep and stress-rupture at higher temperatures. Their high weldability and corrosion resistance in hostile environments make them most suitable for long-term continuous operations at high temperatures. Created for structural integrity and performance over extended periods of service, Incoloy 800H is the best solution for severe thermal and chemical processing situations.

The ideal temperature range for forging Incoloy 800H is between 2100°F and 2250°F (1149°C to 1232°C). This range ensures optimal workability and preserves the material’s mechanical properties.
Post-forging operations for Incoloy 800H typically include annealing to relieve stress and enhance ductility, followed by heat treatment to achieve desired mechanical properties. Surface cleaning and inspection for defects are also essential to ensure quality.
To determine if Incoloy 800H Forgings meet your specific needs, review material specifications, including composition and mechanical properties, and consult with suppliers for customized testing or performance data. Additionally, consider your application's temperature, corrosion, and mechanical requirements.
Incoloy 800H Forgings are commonly employed in processes where oxidation resistance, carburization resistance, and high strength are required. In the petrochemical process, they find application in reactors, reformer tubes, and cracking units. In power generation, they are used in superheater tubes, boiler components, and turbine components. The heat treatment sector uses them for furnace fixtures, retorts, and conveyor systems because of their capacity to resist very high temperatures. They are also employed in heat exchangers, piping, and process equipment that get exposed to corrosive gases and to hot service. Incoloy 800H provides long-term reliability as well as operating efficiency under these severe service conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
