Operating from the heart of Kinshasa, Congo, Sadiki Metals is a trusted source for high-performance materials, proudly supplying industry with essential Hastelloy N bars and rods. We understand the critical demands of modern engineering, which is why we provide this specialized alloy to clients who require unwavering reliability in the most challenging environments. Our commitment is to deliver not just a product, but a durable solution that supports progress and innovation across the region and beyond, backed by local expertise and a dedication to quality.
Hastelloy N is specifically engineered to excel where other materials falter, thanks to its unique composition. It is a nickel-chromium-molybdenum alloy with a significant addition of silicon, creating a remarkable resistance to oxidation and corrosion. This formulation gives the bars and rods exceptional strength and toughness, even when subjected to intense heat and thermal cycling. They maintain their structural integrity under stress, making them a fundamentally robust choice for demanding applications.

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 primary use for these Hastelloy N bars and rods is within advanced industrial and chemical processing systems, particularly those involving molten fluoride salts. You will find them as essential components in nuclear reactors, chemical reactors, and high-temperature heat exchangers. They are also invaluable for fabricating equipment like furnace components and fasteners that must withstand highly corrosive atmospheres. Essentially, they are the go-to material for ensuring safety and longevity in processes where failure is not an option.






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