Our Hastelloy B2 Fasteners offer superb mechanical strength, outstanding thermal stability, and reliable corrosion resistance across a range of aggressive chemical processes. This alloy is composed primarily of nickel and molybdenum, minimizing the formation of grain-boundary carbide precipitates in the weld heat-affected zone. As a result, Hastelloy B2 fasteners are highly resistant to pitting, stress corrosion cracking, and knife-line and heat-affected zone attack, making them suitable for applications in industries like chemical processing, pharmaceuticals, nuclear reactors, and petrochemicals.
