Welcome to Tariku Metals, your trusted partner for industrial solutions in Addis Ababa. We specialize in manufacturing and supplying high-performance Incoloy 800HT forgings, engineered to meet the most demanding challenges. Our commitment to excellence ensures that every component we produce offers unmatched reliability and durability. Whether you’re in energy generation or chemical processing, you can count on us to deliver the robust quality and precise engineering your critical applications require.
The strength of Incoloy 800HT lies in its unique composition, primarily nickel, iron, and chromium, with added aluminum and titanium for stability. This combination gives the forgings exceptional mechanical properties, including high tensile strength and impressive creep-rupture resistance, especially under extreme temperatures. These forgings maintain their structural integrity even when exposed to intense heat and corrosive atmospheres, making them a fundamentally robust material choice for heavy-duty use.

To determine if Incoloy 800HT Forgings meet your specific needs, assess their high-temperature resistance, oxidation, and carburization properties against your application requirements. Consulting with a supplier for detailed material specifications and testing options can also ensure compatibility.
The ideal temperature range for forging Incoloy 800HT is between 2100°F (1149°C) and 2300°F (1260°C). This range ensures optimal workability, mechanical properties, and maintains the material's strength and resistance to oxidation.
Temperature control is crucial for maintaining the desired mechanical properties of forged Incoloy 800HT, as overheating or insufficient heating can lead to reduced strength and ductility. Proper temperature management ensures optimal grain structure, resistance to oxidation, and overall performance in high-temperature applications.
Incoloy 800HT forgings are indispensable in environments where failure is not an option. You will find them at the heart of ethylene furnace systems, critical piping in chemical reactors, and within heat treatment equipment. Their ability to withstand intense heat and pressure makes them perfect for power generation turbines and other high-temperature processing applications. Essentially, wherever extreme conditions threaten ordinary materials, our forgings provide the dependable performance needed to keep operations running smoothly and safely.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
