From the industrial heart of Hamilton, New Zealand, Hemi Metals proudly stands as a trusted manufacturer and supplier, delivering exceptional materials to demanding industries worldwide. Our focus is on providing superior-grade Hastelloy B2 bars and rods, engineered for resilience in the most challenging corrosive environments. We understand that reliability is paramount, which is why we ensure every length of Hastelloy B2 we supply meets the highest standards of quality and performance, directly supporting the critical work of our clients with local expertise and global reach.
Hastelloy B2 is a nickel-molybdenum alloy specifically formulated for outstanding resistance to hydrochloric acid across a wide range of concentrations and temperatures. Its low carbon and iron content minimizes the formation of undesirable secondary phases, ensuring excellent stability. This composition gives the alloy remarkable mechanical strength, good ductility, and superior toughness, even after welding. These bars and rods are built to maintain their integrity under severe thermal and mechanical stress, providing a reliable solution where other materials would quickly fail.

Yes, Hastelloy B2 rods can be welded. However, it requires proper techniques and filler materials to avoid cracking due to their sensitivity to heat-affected zones.
Hastelloy B2 bars offer exceptional resistance to hydrochloric acid and other corrosive environments, along with excellent weldability and high strength. They are highly resistant to pitting, stress corrosion, and localized corrosion.
Hastelloy B2 rods are available in various sizes, ranging from small diameters to larger rods, with common diameters including 0.125 inches to 4 inches. They typically come in a polished or cold-drawn finish, depending on the application requirements.
The unique properties of Hastelloy B2 bars and rods make them indispensable in sectors where aggressive chemical exposure is a daily reality. You will find them at the core of chemical processing equipment, such as reactors, distillation columns, and pipelines handling hydrochloric acid. They are also vital in the production of pharmaceuticals, acetic acid, and other specialty chemicals. These robust components are essential for constructing fixtures, shafts, and fasteners that must endure corrosive atmospheres, ensuring long-term operational safety and efficiency in plants around the globe.






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