Use of higher-alloyed metallic materials and duplex steels for transport tanks of dangerous goods

  • Compatibility evaluations of selected metallic materials under the influence of dangerous goods are published in the BAM-List - Requirements for Tanks for the Transport of Dangerous Goods” as basis for substance-related prototype approvals for tank Containers designed for the carriage of dangerous goods. There is a request of the tank manufacturing industry and transportation Companies to incorporate additional materials into the BAM-List, especially corrosionresistant materials because of the large number of corrosive dangerous goods. One solution to solve corrosion Problems is to line the tank with a polymeric material, an alternative solution is the application of high-alloyed stainless steels and nickel-based alloys as there are alloy 926 (1.4529), alloy 31 (1.4562) and alloy 59 (2.4605). But there is an interest to use cost-efficient steels with high strength values and concomitant adequate corrosion resistance such as duplex Steel 1.4362 too.

But there is an interest to use cost-efficient steels with high strength values and concomitant adequate corrosion resistance such as duplex Steel 1.4362 too. This Steel grade was originally developed as a substitute for the austenitic grades 1.4404 and 1.4571. Due to the lower content of the alloy elements nickel and molybdenum this duplex steel is a cost-efficient alternative to molybdenum containing austenite. Due to the limited number of corrosion test results with welded test samples of these high-alloyed materials and the duplex steel under the influence of corrosive dangerous goods a comprehensive test Programme was performed with these materials in Cooperation with ThyssenKrupp VDM and Deutsche Edelstahlwerke GmbH. It can be concluded from the test results that the "superaustenitic steels” 1.4529 and 1.4562 as well as the nickel-based alloy 2.4605 are a really good alternative as tank materials for the transport of dangerous goods in comparison to the lining of the tanks. Due to the reduced alloying content, in particular Nickel (3.7 %) and Molybdenum (0.15 %), a lower resistance of the duplex steel 1.4362 compared to the austenitic CrNiMo-steels was observed in acidic media. The duplex Steel is an alternative to the austenitic steels, especially in alkaline media. The test results are included in the current 10th edition of the BAM-List and therefore available for the costumer.zeige mehrzeige weniger
