Hastelloy B-3 stands as a nickel-molybdenum alloy renowned for its remarkable resistance to pitting, corrosion, and stress-corrosion cracking, coupled with thermal stability surpassing that of Alloy B-2. Moreover, this Hastelloy variant exhibits outstanding resistance to intergranular and weld-affected zone attack. Its superior thermal stability reduces the challenges associated with the fabrication of Alloy B-2 components, attributed to its diminished propensity for detrimental intermetallic phase precipitation during thermal cycling, thus affording greater flexibility than Hastelloy B-2 during and after various thermal conditions.
Hastelloy B-3 represents a specific grade within the Hastelloy family, characterized by its nickel-molybdenum composition. Hastelloy encompasses various grades, among which B-3 is optimized for distinct purposes. The inclusion of molybdenum enhances Hastelloy's hardness and strength at elevated temperatures, rendering it well-suited for welding applications. These nickel-based alloys are easily fabricated and machined, showcasing exceptional ductility and suitability for cold working processes.
