Hastelloy B3 is a nickel-molybdenum alloy of the Hastelloy B series. It optimizes the composition based on the B2 alloy to improve thermal stability, intergranular corrosion resistance and welding performance. The core advantage is its excellent corrosion resistance to strong reducing media, while solving the problem of the early B series alloys easily precipitating brittle phases after hot working or welding. At the same time, Hastelloy B3 alloy has excellent corrosion resistance to hydrochloric acid at any temperature and concentration.
Hastelloy B3 can also withstand non-oxidizing media such as sulfuric acid, acetic acid, formic acid, and phosphoric acid.The distinguishing feature of Hastelloy B3 is that it retains excellent ductility during transient exposure to moderate temperatures. This exposure often occurs during thermal processing associated with manufacturing.
JN has a large stock of Hastelloy B3, with complete material specifications and can provide original material guarantees. Welcome to inquire.
