Sets of static, corrosion tests were performed to evaluate candidate materials being considered for use with standard HDA High Density Acid, since the latter was known to be relatively corrosive. The tests were performed at temperatures and times representative of anticipated service conditions for each material. Measurements and observations were made both for changes in the acid and the material. This included chemical analyses and corrosion rates calculated from changes in weight. Based on the results, the materials were ranked in one of four categories, ranging from satisfactory for general use to unsatisfactory. A number of aluminum alloys fell in the former category. Stainless steels appear good for limited use. Results for all materials are tabulated in the text.
