Welcome to Maduka Metals, your trusted partner for premium industrial materials right here in Abuja. We specialize in providing high-performance Hastelloy N bars and rods, engineered to meet the most demanding challenges. Sourced from leading producers and backed by our commitment to quality and reliable supply, we ensure our clients receive materials that guarantee longevity and superior performance in even the toughest environments, supporting the growth and integrity of Nigeria’s key industries.
Hastelloy N is specifically formulated with a nickel-chromium-molybdenum alloy, with a key addition of silicon that gives it exceptional stability. This unique composition grants it outstanding resistance to oxidation and corrosion, particularly against molten fluoride salts. The resulting mechanical properties are impressive, offering high tensile strength and excellent creep resistance at elevated temperatures, which ensures structural integrity and reliability under intense thermal and mechanical stress.

Yes, Hastelloy N rods can be welded using standard welding techniques, including TIG and MIG welding. Preheat and post-weld heat treatment may be required for optimal results.
Hastelloy N rods are available in various sizes, typically ranging from 1/8" to 3" in diameter. They come with finishes such as cold drawn, bright annealed, or polished, depending on the application.
Hastelloy N bars offer exceptional corrosion resistance, particularly in high-temperature environments. They also exhibit excellent strength, thermal stability, and resistance to oxidation and carburization.
The unique capabilities of Hastelloy N bars and rods make them indispensable in specialized fields. You will find them at the heart of chemical processing equipment, nuclear reactors, and aerospace components where exposure to extreme temperatures and aggressive media is common. They are also crucial in manufacturing fixtures for heat treating, furnace components, and in pioneering research environments, proving essential for any application that demands unwavering resilience against severe thermal and corrosive challenges.
