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 exceptional properties of Hastelloy B3 bars and rods make them indispensable in industries where failure is not an option. You will find them at the heart of chemical processing equipment, handling aggressive acids like hydrochloric and sulfuric. They are essential in pharmaceutical manufacturing, pollution control systems, and pickling operations. Whether used for shafts, fasteners, or valve components, these materials ensure integrity and safety in environments that would quickly degrade lesser metals.






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