STAINLESS STEELS FOR TANKER CONSTRUCTION

In "special" tankers, the interaction between the cargo-tank material and liquid cargoes such as chemicals, acids, and winces can often be avoided by coating or lining the tanks, if the same product is always carried. However, where the type of cargo is subject to change, the tank should be of a material that remains passive and which can be quickly and thoroughly cleaned; these requirements can be met by stainless steels. The Author describes the several stainless steels available for these applications, in particular the austenitic steels (to DIN and AISI specifications) used in Germany, explains the effects of some of the alloying elements, and discusses the choice of material that has to be made when a new tanker of this type is being planned. It is mentioned that, apart from the standard specifications, special stainless steels can be "made to measure" for particular applications. The surface condition of stainless steels used in tank construction is of the utmost importance for their chemical resistance; finish and cleanliness are discussed, and the DIN standard applicable to surface finish is briefly explained. Some precautions to be taken before a tank is put into service are mentioned. The question of whether to use solid stainless-steel plate, or clad plate (ordinary steel plate, usually ship plate, with rolled-on stainless-steel cladding), is a difficult one to answer. Its technical and economic implications are discussed, and a general recommendation is that both materials should be used, each to its best advantage. Order from: BSRA as No. 47,676.
