The presence of exogenous surface contaminants may adversely affect Hastelloys natural corrosion-resistant properties. Surface contaminants, including grease, dirt, iron, and other metallic particles are inherent to the metal fabrication process. During the passivation of Hastelloy, the surface of a part is chemically treated by a mild oxidant. The chemical passivation treatment removes free iron and other foreign contaminants, allowing the Hastelloy to perform and resist corrosion as it is engineered to do.
Harrison Electropolishing has performed Hastelloy passivation treatments with excellent results for decades. We have the capacity to passivate Hastelloy components of all sizes. Harrison Electropolishing will perform chemical passivation treatments in compliance with ASTM specifications or your industry or company specific chemical passivation standard.
