The Hastelloy B2 flanges are Nickel and Molybdenum bearing Flanges that offer excellent resistivity against reducing environments. These flanges are Solid solution strengthened. The Molybdenum content in these flanges provides significant corrosion resistance against a range of reducing environments. The Nickel Content helps these flanges to resist the formation of grain-boundary carbide precipitates in the weld heat-affected zone. The Hastelloy B2 Flanges are reliable for applications in environments that contain reducing agents such as phosphoric acids, sulfuric acid, acetic acid, and hydrogen chloride gas. They also have excellent resistance to pitting and stress corrosion cracking, even at heat-affected zones and knife-line zones.
The Hastelloy B2 Flanges are highly resistant against hydrochloric acid at all temperatures and concentrations. They also offer resistivity to pure sulfuric acid and different non-oxidizing acids. The Hastelloy b2 Flanges are not recommended for applic
