Effects of Various Elements on the Hydrochloric Acid Resistivity of Nickel-Molybdenum-Chromium Alloys
Year: 1950
Type: article
Abstract: The purpose of this research is to improve the hydrochloric acid resistivity of molybdenum-chromium-nickel-base alloys by addition of various elements.Ferro-vanadium,ferro-tantalum,ferro-titanium, ferro-zirconium, copper-beryllium, wolfram, cobalt and copper were respectively added to various high-molybdenum-high-chromum-nickel-base alloys.The corrosion tests were carried out in 10, 20 and 30 per cent hydrochloric acid at room temperature and 10 and 20 per cent hydrochloric acid at boiling point. Ferro-vanadium was most effective and 30 per cent molybdenum-15 per cent chromium-0.5 per cent ferro-vanadium-nickel base alloy was not attacked at all for 15 days in 10 per cent hydrochloric acid at room temperature. Except ferro-vanadium, other elements gave rather bad effects, especially ferro-titanium was the worst of all.
