In this post, crevice corrosion resistance performance of Inconel and Hastelloy is evaluated in 3.5% NaCl solution at 60oC. The presence of chromium and molybdenum in these corrosion resistant alloys is found significant. It has been found that these elements have a crucial role in retaining and stabilizing the passivity of Inconel and Hastelloy grades … Continue reading Crevice corrosion resistance performance of Inconel and Hastelloy

Gaseous chlorine at mild temperatures and without moisture is not extremely attacking and is easily handled by carbon steel. Dry hydrogen chloride (HCl) acts in the same manner. Although, the highly acidic HCl adversely affects steel. Corrosion Corrosion is a complicated process, probably unessential factors for example minor magnitude of moisture, contaminants or availability of … Continue reading Alloys Resisting Chloride Media
