... material for marine cargo applications, having been installed in 14 cargo ships since 1987 ( Ref 5 ). Figure 3 compares the corrosion resistance of 316, 317, and cast alloy 20 (UNS N08007) in 105% super-phosphoric acid (76% P 2 O 5 ) ( Ref 6 ). Note that all of the alloys show less than 0.25 mm/yr...

... and the nature of the particulates and fluid. Erosion-corrosion of a UNS N08007 (ACI CN-7M) stainless steel cast impeller after exposure to hot concentrated H 2 SO 4 with solids present is shown in Fig. 7 . Erosion-corrosion is also evident in Fig. 8 , which shows that the erosion-corrosion damage increased...
