CORROSION RESEARCH SURVEY

Abstract

CHROMIUM STEEL Corrosion of 13% chromium steel under everyday conditions. Excellent experience has been gathered with 13% chromium steel under many conditions of daily practice. Occasionally, however, unexpected cases of corrosion are encountered. This is most frequently the case where town water with, e.g. 100 mg./l. Cl? and relative air humidity of 75 to 85%, evaporates on to this steel. In this case, highly concentrated chloride solutions are formed which are liable to attack the steel. A low sulphide content greatly favours the corrosion of 13% chromium steel caused by chloride solutions. Particularly strong corrosion is caused by acetic acid containing copper chloride which may be formed through the action of acid foods on cutlery made of alpaca. If, in such a solution, silver is in contact with the chromium steel, pit corrosion rates of up to 10 ?/ hr. may occur.—G. Schikorr, Werks. u. Korr., 1962, 13 (10), 606–611.
