Nestled in the industrial hub of Safat, Kuwait, Nimish Metal has built a reputation as a trusted supplier of high-performance materials. We proudly offer a comprehensive range of Hastelloy N bars and rods, catering to the demanding needs of various specialized industries. Our commitment is to provide not just premium products, but also reliable service, ensuring that our clients have the robust materials they need to build, maintain, and innovate with confidence, backed by our local expertise and global standards of quality.
Crafted from a nickel-chromium-molybdenum alloy with additions of silicon and tungsten, Hastelloy N is engineered for exceptional stability. Its standout feature is an impressive resistance to corrosion from molten fluoride salts, even at extremely high temperatures exceeding 1300°F (700°C). This unique composition also imparts excellent thermal stability and good mechanical strength, making these bars and rods exceptionally durable in challenging thermal and chemical environments where other materials would quickly degrade.

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 properties of Hastelloy N bars and rods make them indispensable in advanced technology sectors. They are primarily used in nuclear reactors, particularly in components exposed to molten fluoride salts, thanks to their superb resistance. You’ll also find them in aerospace applications, chemical processing for aggressive environments, and in specialized equipment for the pharmaceutical and industrial heating industries, where reliability under extreme thermal stress is an absolute necessity for safety and operational success.






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