Hastelloy B-3｜Alloy B 3｜N10675｜Pipe and Tube
Hastelloy B-3 alloy is a Ni-Mo corrosion-resistant alloy and also a low-carbon alloy. To solve the technical problems caused by insufficient stability, while retaining the corrosion resistance characteristics of B2, it solves the problems of welding cracks and fracture during processing. And this alloy also has better corrosion resistance than B2. It has good corrosion resistance at any temperature and concentration of HCl, and also has good corrosion resistance to H2SO4, CH3COOH, formic acid, H3PO4, and other non oxidizing media. Moreover, due to the adjustment of its chemical composition, its thermal stability has been significantly improved compared with B2, and it has high resistance to spot corrosion, stress corrosion cracking, knife corrosion, and corrosion in the Heat-affected zone of welding. The tendency to form harmful phases between metals is minimal, making it more resilient than B-2 during heating and subsequent various forms of thermal cycling.
