Based in the heart of Hamilton, New Zealand, Hemi Metals has built a strong reputation as a reliable manufacturer and supplier of high-performance alloys. We take particular pride in our expertise with Hastelloy B3 bars and rods, a material chosen for the most demanding industrial environments. Our team understands that your projects require materials you can count on, which is why we ensure our Hastelloy B3 stock meets the highest standards for quality and consistency, providing a dependable local source for critical components.
Hastelloy B3 is engineered with a nickel-molybdenum composition that provides exceptional resistance to hydrochloric acid at various concentrations and temperatures. This advanced alloy also stands up to sulfuric, acetic, and phosphoric acids. Its mechanical strength is impressive, offering excellent tensile and yield strength while maintaining good ductility and fabricability. This combination allows it to perform reliably under high stress and in corrosive settings where other materials would quickly fail.

Hastelloy B3 bars offer exceptional resistance to hydrochloric acid, excellent weldability, and superior corrosion resistance in aggressive environments. They also provide high strength and durability at elevated temperatures.
Yes, Hastelloy B3 rods can be welded using appropriate welding techniques. It is important to control heat input to avoid potential cracking or damage to the material.
Hastelloy B3 rods are available in various sizes, typically ranging from small diameters (1/8" to 1") to larger dimensions depending on the application. They are commonly offered in finishes such as cold-finished, hot-rolled, or polished for specific requirements.
The unique properties of Hastelloy B3 bars and rods make them essential in sectors where failure is not an option. You’ll find them at the core of chemical processing equipment, such as reactors, distillation systems, and piping where harsh acids are present. They are also vital in the pharmaceutical industry for manufacturing processes and in pollution control systems like scrubbers. Essentially, wherever severe corrosion is a primary concern, Hastelloy B3 provides the long-lasting, maintenance-free performance that keeps operations running smoothly and safely.
