Hastelloy B-3 Bar Description

Hastelloy B3 is a nickel-based high-temperature alloy, mainly composed of nickel, molybdenum, cobalt and other elements. This alloy material is optimized on the basis of Hastelloy B2.  Improving the thermal stability of the material significantly enhances the corrosion resistance, while also effectively improving the hot forming and cold forming performance. Hastelloy B3 bars have been increasingly used in the production and manufacturing of chemical equipment. Besides, Hastelloy B3 material has many unique properties. Its high elongation provides favorable conditions for cold forming operations. Compared to austenitic stainless steel, Hastelloy B3 bar is harder and therefore requires greater pressure during cold forming or step forming processes.
