Welcome to Maduka Metals, your trusted partner for industrial solutions right here in Abuja. We specialize in providing high-performance Hastelloy C22 forgings, engineered to meet the most demanding challenges. In an industry where reliability is non-negotiable, our products stand as a testament to superior quality and durability, offering exceptional resistance where other materials might fail. We are proud to supply locally manufactured components that empower key sectors across Nigeria and beyond, ensuring our clients receive not just a product, but a promise of unwavering performance and support.
The exceptional strength of Hastelloy C22 forgings comes from a carefully balanced composition, primarily nickel with significant amounts of chromium and molybdenum. This blend gives the material its remarkable mechanical properties, including high tensile strength and excellent ductility, allowing it to be forged into complex, heavy-duty shapes. It maintains these robust characteristics even when subjected to extreme temperatures and intense pressure, ensuring the final component is not just tough, but reliably consistent in the most punishing operational environments.

Yes, Hastelloy C22 can be forged into custom shapes, as it has good formability and strength at elevated temperatures. However, it requires precise control during the forging process to maintain its properties.
The ideal temperature range for forging Hastelloy C22 is between 2,100°F (1,150°C) and 2,300°F (1,260°C). This ensures optimal formability and minimizes the risk of damaging the material's properties.
The forging process for Hastelloy C22 typically takes several minutes to hours, depending on the complexity and size of the part. The heating and cooling cycles also influence the total time required for forging.
The true value of Hastelloy C22 forgings is realized in their wide-ranging applications, particularly within the chemical processing, oil and gas, and power generation industries. These components are essential in equipment like pumps, valves, and reactor vessels where exposure to highly corrosive chemicals, seawater, or acidic conditions is a daily reality. By choosing these forgings, engineers can significantly extend the lifespan of critical machinery, reduce maintenance downtime, and enhance operational safety, making them a smart, long-term investment for any serious industrial operation.
