 note = {Duplex stainless (SUS329J3L) clad steel plate is newly developed and commercialized in 2016.  The fundamental problem to be solved for the utilization of SUS329J3L clad steel plate in chemical tanker construction is to secure the strength and reliability on the bonded interface of SUS329J3L clad steel plate. In this study, the fracture toughness, fatigue crack propagation characteristics of the bonded interface of SUS329J3L clad steel plate and fatigue strength of the welded joints of the clad steel plates were investigated and also the weldability and corrosion resistance of the clad steel plate were evaluated.   The results can be summarized as follows.
①　From the results of fracture toughness tests using cruciform welded joint specimens and CT type specimens of the bonded interface of SUS329J3L clad steel plate and fatigue crack propagation tests using CT type and CCT type specimens of that, we concluded that duplex stainless (SUS329J3L) clad steel plate can be sufficiently utilized in chemical tanker construction.
②　The fatigue strength of cargo tank structure of chemical tanker using a combination of SUS329J3L clad steel plates and SUS329J3L solid steel plates is equal or superior to that of cargo tank structure using a conventional combination of austenitic stainless (SUS316L) clad steel plates and SUS316LN solid steel plates.
③　Through the evaluation of the weldability of tested clad steel plates, we clarified the fact that SUS329J3L clad steel plates are equal or superior to SUS316L’s in the various strength characteristics and weldability.
④　In terms of the corrosion resistance, it was clarified that the cladding material of SUS329J3L steel plate is equal or superior to that of SUS316L steel plate.},
