The BAM-List - Requirements for Tanks for the Carriage of Dangerous Goods - is used as the basis for the substance-related prototype approvals for tank containers and portable tanks designed for carriage of dangerous goods in Europe [1]. In the BAM-List’s 6 th issue more than 400 substances are listed which are corrosive to the commercially used tank materials (unalloyed, austenitic CrNi- and CrNiMo-steels). Chemical companies, transportation providers and tank producers need tanks made of corrosion resistant materials. One possibility to solve the corrosion problems is to line the tank with a polymeric material, another one is the application of high-alloyed stainless steels and nickel-based alloys as there are X1NiCrMoCuN25-20-7 (alloy 926), X1NiCrMoCu32-28-7 (alloy 31) and NiCr23Mo16Al (alloy 59). The Federal Institute for Materials Research and Testing (BAM), IKS Dresden and ThyssenKrupp VDM started an exposure test program with welded specimens in selected corrosive dangerous goods. The three high-alloyed materials were tested in substances representing 12 groups of dangerous goods like inorganic halogenides, organic acidic halogenides, halogenic carbonic acids, chlorosilanes, chlorates, perchlorates chlorites, hypochlorites, hydrogen sulphates, sulfides, sulphuric and nitric acids, chloric and perchloric acids, chlorosulphonic acids and phosphoric acids. The results will be incorporated in the 8 th issue of the BAM-List to extend the numbers of corrosion-resistant tank materials.
