Based in the heart of Kinshasa, Congo, Okoye Nickel Alloys stands as a key supplier for some of the most challenging industrial environments. We understand that reliability isn’t just a preference; it’s a necessity. That’s why we specialize in providing high-performance Hastelloy C22 coils, materials chosen for their unparalleled resistance to corrosion. Whether your project is in chemical processing or power generation, we deliver coils that are built to endure, ensuring your operations run smoothly and efficiently against even the harshest conditions.
Hastelloy C22 is primarily composed of nickel, with significant additions of chromium and molybdenum, creating a robust foundation. This alloy is further fortified with tungsten and a very low carbon content, a combination that gives it a remarkable balance of strength and ductility. It maintains excellent mechanical integrity across a wide temperature range, resisting everything from pitting and crevice corrosion to the damaging effects of oxidizing chemicals. This makes it a material you can trust to hold its shape and strength under intense pressure.
