Comparative 0.1 mm/y Line Plots

To compare the performance of ULTIMET® alloy with that of other materials, it is useful to plot the 0.1 mm/y lines. In the following graphs, the lines for ULTIMET® alloy are compared with those of two popular, austenitic stainless steels (316L and 254SMO), and two nickel alloys (625 and C-22®), in hydrochloric and sulfuric acids. The tests in hydrochloric acid were limited to a concentration of 20% (the azeotrope). At hydrochloric acid concentrations up to 15%, the performance of ULTIMET® alloy exceeds that of alloy 625, and in sulfuric acid, the performance of ULTIMET® alloy matches that of alloy 625 at many concentrations.
