High alloy special stainless steels and Ni base alloys have for the transportation of hazardous water polluting substances and waste media a wide range of applications. This has been proved in laboratory tests for the materials Cronifer 1925 hMo (1.4529), Nicrofer 3127 hMo (1.4562) and Nicrofer 5923 hMO (2.4605) as well as, in the case of Cronifer 1925 hMo, via evaluation of data from the literature. Cronifer 1925 hMo possesses resistance to halide containing solutions as well as to a large number of acids over a wide range of concentrations. While the advantages of Nicrofer 3127 hMo over Cronifer 1925 hMo were evident in only a few of the media under investigation, the corrosion resistance of Nicrofer 5923 hMo was clearly superior. Based on the evaluated literature data and the data of laboratory tests Cronifer 1925 hMo has been qualified as tank material for the transportation of over 1000 media.
