Welcome to Tariku Metals, your trusted partner in Addis Ababa for uncompromising industrial solutions. We take pride in manufacturing and supplying superior Incoloy 800H forgings, engineered to meet the most rigorous demands. Our commitment lies in delivering components that offer exceptional strength and longevity, directly supporting Ethiopia’s growing industrial and energy sectors with reliable, high-performance materials you can count on for your critical projects.
The strength of Incoloy 800H comes from its carefully balanced composition of nickel, iron, and chromium, enhanced with titanium and aluminum. This specific blend is heat-treated to deliver outstanding mechanical properties, including high tensile strength and remarkable creep resistance, especially under extreme temperatures. These forgings are specifically designed to maintain their integrity and performance in the most challenging thermal and corrosive environments.

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.
In practice, these robust forgings are essential in demanding sectors. They are commonly used for critical components in high-temperature industrial furnaces, heat treatment equipment, and power generation systems. You will also find them performing reliably within the chemical processing industry, handling aggressive substances, and in vital petrochemical applications where their resistance to carburization and oxidation prevents equipment failure and ensures long-term operational safety and efficiency.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
