At Nimish Metal, located in the industrial heart of Safat, Kuwait, we take pride in providing exceptional materials for the most demanding industrial environments. Our Hastelloy B2 Bars and Rods are specifically chosen for their outstanding resistance to hydrochloric acid and other severe reducing conditions. We understand that reliability is paramount, which is why we ensure that every bar and rod we supply meets the highest standards of quality and performance, giving our clients the confidence to tackle their toughest chemical processing challenges with ease.
The strength of Hastelloy B2 lies in its precise composition, primarily a nickel-molybdenum alloy that is meticulously balanced to eliminate any iron content. This unique formula grants it superior resilience against pitting and stress-corrosion cracking. The resulting mechanical properties are impressive, offering high tensile strength and excellent ductility, even after prolonged exposure to extreme temperatures. This combination ensures that components made from these bars are not only durable but also reliable under significant mechanical stress.

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.
You’ll find Hastelloy B2 Bars and Rods at work in some of the most critical applications across industries. They are indispensable in the construction of reactors, distillation columns, and piping systems within chemical plants that handle aggressive media like hydrochloric and sulfuric acid. They are also vital for components in pollution control systems, pharmaceutical production, and pickling operations, where failure is not an option. Choosing this material means investing in long-term performance, minimizing downtime, and ensuring operational safety where corrosion is the primary enemy.






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