Hastelloy B3 Fasteners are leaders among suppliers and manufacturers, celebrated for their exceptional resistance to hydrochloric acid at all concentrations and temperatures. With enhanced structural stability compared to its predecessors, Hastelloy B-3 reduces challenges during welding, fabrication, and service. This nickel-molybdenum alloy excels in resisting pitting, corrosion, and stress-corrosion cracking, while also offering superior thermal stability over alloy B-2.
Hastelloy UNS N10675 Fasteners are widely used in aircraft, furnace components, chemical processing equipment, honeycombs, and gas turbine combustion section components. The alloy boasts excellent resistance to sulfuric, acetic, formic, and phosphoric acids, as well as other non-oxidizing media. The unique chemistry of B-3 Alloy Fasteners provides enhanced thermal stability over its predecessors, particularly surpassing HASTELLOY B-2 alloy. Renowned for its corrosion resistance in non-oxidizing environments like HCl, HASTELLOY B-3 Din 2.4617 Fasteners stand out as a key addition to the Ni-Mo alloy family, with specially engineered chemistry for improved performance.Specifications of Duplex 2205
