Welcome to Maduka Metals, your trusted partner in Abuja for premium industrial materials. We take pride in manufacturing and supplying high-performance Hastelloy C276 forgings, engineered to meet the most demanding challenges. Our commitment is to provide local industries with reliable, durable components that ensure longevity and efficiency in critical operations, supporting the growth and resilience of Nigeria’s key sectors with top-tier, readily available solutions.
Hastelloy C276 is a nickel-molybdenum-chromium alloy renowned for its exceptional resistance to a wide range of severe corrosive environments. It maintains impressive strength and toughness even at elevated temperatures, offering excellent protection against pitting and stress-corrosion cracking. This combination of durability and mechanical integrity makes it a go-to material for components that must perform reliably under extreme chemical and thermal stress.

Post-forging operations for Hastelloy C276 include heat treatment (such as annealing) to relieve stresses and improve mechanical properties, followed by surface finishing (like pickling or grinding) to remove oxides and enhance corrosion resistance.
To determine if Hastelloy C276 forgings meet your needs, assess their chemical composition, mechanical properties, and resistance to corrosion under the specific conditions of your application. Conduct testing such as tensile, impact, and corrosion tests for confirmation.
The ideal temperature range for forging Hastelloy C276 is between 1,900°F and 2,200°F (1,038°C to 1,204°C). This ensures proper deformation without compromising material properties.
The robustness of our Hastelloy C276 forgings makes them indispensable in sectors where failure is not an option. They are vital in chemical processing for reactors and pumps, in pollution control systems for scrubbers, and in the oil and gas industry for wellhead components. You’ll also find them performing critical roles in pharmaceuticals and pulp and paper production, wherever aggressive chemicals or high temperatures are part of the daily operation, ensuring safety and uninterrupted productivity.






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