For manufacturers in Hamilton and beyond tackling some of the industry’s most aggressive environments, Hemi Metals stands as a reliable local source for high-performance alloys. Specializing in Hastelloy N bars and rods, we provide essential components crafted from a material designed to excel where others fail. Our focus is on delivering robust, ready-to-machine stock that empowers New Zealand’s industrial and research sectors to build equipment with uncompromising integrity and a significantly extended service life.
The strength of Hastelloy N lies in its unique makeup, primarily nickel with significant additions of molybdenum and chromium. This specific composition grants it truly remarkable mechanical properties, including excellent tensile strength and good creep-rupture resistance at elevated temperatures. Perhaps most critically, it maintains impressive ductility and toughness after extended exposure to extreme heat, ensuring components don’t become brittle over time.

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.
These bars and rods are indispensable in applications demanding resistance to molten fluoride salts and high-temperature oxidation. You’ll find them at the heart of nuclear reactor components, chemical processing equipment, and aerospace assemblies. They are also vital for fixtures in heat-treating furnaces and for fabricating vessels that handle corrosive catalysts. Essentially, any situation involving extreme temperatures combined with highly corrosive agents is where Hastelloy N proves its invaluable worth.
