A nickel-molybdenum grade, Alloy B-2 is extremely resistant to hydrochloric acid in a wide range of temperatures.
Alloy B-2 is a solid-solution strengthened nickel alloy which is normally used in extreme reducing conditions. Alloy B-2 also exhibits good resistance to hydrogen chloride, sulphuric acid and phosphoric acid.
We stock Alloy B-2 in round bar form, available in a wide range of sizes to suit different chemical processing and corrosion-resistant applications. To view available sizes and submit an inquiry, use the dropdown selector below.
Alloy B-2 is a nickel-molybdenum alloy with significant resistance to reducing environments, such as hydrogen chloride gas and sulphuric, acetic and phosphoric acids. Hastelloy® B-2 provides resistance to pure sulphuric acid and a number of non-oxidising acids. The alloy should not be used in oxidising media or where oxidising contaminants are available in reducing media. Premature failure may occur if alloy B-2 is used where ferric iron, cupric ion and free chlorides are present.
With a high nickel content, Hastelloy® B-2 is immune to chloride-induced stress corrosion cracking.
