Comparison of the corrosion resistance to dangerous goods of austenitic CrNiMo and duplex steels
- The “BAM-List - Requirements for Tanks for the Transport of Dangerous Goods” is the basis in Germany for substance-related prototype approvals for tank Containers in Germany. Compatibility evaluations of selected metallic materials and polymeric materials under the influence of approximately 7200 dangerous goods have been published in the BAM-List since 1989. The austenitic CrNi- and CrNiMo-steels - UNS S30403, UNS S31600, UNSS31603 and UNS S31635 - are the materials mostly used worldwide for transport tanks. The duplex Steel UNS S31803 has been put on the BAMList due to the great interest of tank producers and transport Companies. Using UNS S31803 instead of 316L, the weight of the tanks can be reduced, and the list of transportable goods can be extended. The objective of these investigations was to compare the corrosion resistance of duplex Steel UNS S31803 and austenitic Steel UNS S31603. Therefore, test specimens of both steels were exposed to selected corrosive substances, such asThe “BAM-List - Requirements for Tanks for the Transport of Dangerous Goods” is the basis in Germany for substance-related prototype approvals for tank Containers in Germany.

The objective of these investigations was to compare the corrosion resistance of duplex Steel UNS S31803 and austenitic Steel UNS S31603. Therefore, test specimens of both steels were exposed to selected corrosive substances, such as formic acid, acetic acid, phosphoric acid, sulfuric acid, nitrating acid, monochloroacetic acid and trichloroacetone at 55 °C (30 °C, 70 °C). The test results have shown that the duplex Steel UNSS31803 is a good alternative to austenitic CrNiMo-steel UNS S31603 for tanks carrying corrosive dangerous goods.…
