About Hastelloy B-2
Nickel-Molybdenum Alloy Hastelloy B-2 features excellent resistance to reducing conditions like hydrogen chloride gas, sulfuric acid, acetic acid and phosphoric acid. The alloy is resistant to various organic acids and chloride ion stress corrosion cracking. Suitable for use in various conditions including a variety of non-oxidizing acids. It is not recommended for use in presence of oxidizing materials such as cupric or ferric salts. Early failure may take place if this Nickel alloy is employed in hydrochloric acid conditions containing iron or copper.
The availability of carbon, silicon and iron elements tends to lower reduction rate of corrosion resistance property of alloy B2 in welded form. Limiting content of other alloying elements like iron and chromium has solved other problems such as fabricability. Nickel B2 with controlled composition can be employed in the welded form and it is less prone to stress corrosion cracking in the several conditions.
Nickel alloy B2 prevents the production of grain boundary carbides in the weld HAZ, therefore its as-welded form is suitable for use in the chemical processing environments.
