Welcome to Maduka Metals, your trusted partner for high-performance materials right here in Abuja. We specialize in supplying and manufacturing premium Incoloy 800 forgings, providing local industries with robust components that stand up to the most demanding conditions. Our focus is on delivering not just a product, but a reliable solution backed by deep expertise and a commitment to supporting Nigeria’s growing industrial sector with quality you can depend on.
Incoloy 800 is a remarkable nickel-iron-chromium alloy strengthened by its titanium and aluminum content. This specific composition gives the forgings outstanding mechanical strength and excellent resistance to oxidation and carburization, especially in high-temperature environments. The forging process further refines the alloy’s grain structure, resulting in components with superior toughness and creep resistance, making them incredibly durable under sustained stress and thermal cycling.

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.
The resilience of our Incoloy 800 forgings makes them indispensable in sectors where failure is not an option. They are commonly used in critical components for industrial heating furnaces, heat treatment equipment, and nuclear power generation systems. You’ll also find them performing reliably in chemical processing plants, handling corrosive environments, and within the petrochemical industry for tubing hangers and other essential hardware that must endure extreme pressures and temperatures day in and day out.






We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
