Caractéristiques: Hastelloy B-2 has outstanding resistance to hydrochloric acid at all concentrations and temperatures. It also has significant resistance to reducing environments like sulfuric, phosphoric, acetic acids and other nonoxidizing media. Hastelloy B-2 has excellent resistance to pitting corrosion, stress corrosion cracking, and knife line and weld heat-affected zone attack. Hastelloy B-2 has poor resistance to oxidizing environments, therefore, it should not be used where ferric or cupric salts are present as these salts may cause rapid corrosion failure.
Applications: Manipulation d'équipements réduisant les environnements chimiques; et l'industrie des procédés chimiques impliquant les acides chlorhydrique, sulfurique, phosphorique et acétique.
