Hastelloy B2 pipes with excellent resistance to corrosion in aggressive reducing media
Controlling other alloying elements such as iron and chromium
Hastelloy B2 Hexagonal Pipes also resists pitting and crevice attack in ferric chloride test that is significantly used in the chemical process industry, FGD and pulp and paper applications. 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.
