Material Summary
The extremely low carbon and silicon content of Alloy B2 reduces precipitation of carbides and other phases in the heat-affected zone of welds and ensures adequate corrosion resistance even in the welded condition.
Alloy B2 exhibits excellent corrosion resistance in aggressive reducing media such as hydrochloric acid in a wide range of temperatures and concentrations, as well as in medium-concentrated sulphuric acid even with limited chloride contamination. It can also be used in acetic and phosphoric acids. Optimum corrosion resistance can be obtained only if the material is in the correct metallurgical condition and exibits a clean structure.
