Pure phosphoric acid has no influential oxidizing power and is categorized as a non-oxidizing acid as dilute sulfuric acid. Industrial phosphoric acid, although often contains contaminants like fluorides and chlorides that remarkably improve its corrosivity. Oxidizing compounds like ferric salts may also be available to influence corrosion. Probably due to change in magnitudes of impurity … Continue reading Alloys for Performance in Phosphoric acid

Nitric acid is a strong oxidizing agent hence, alloys offering the excellent resistance are those which produce passive oxide layers. The alloys containing crucial magnitude of chromium provide superior resistance as compare to those having lesser Cr content. While nickel based alloys provide high resistance to pure nitric acid,these are specifically effective in the combined … Continue reading Nickel based alloys- Performance in Nitric acid
