Abstract
Rolled titanium clad plates which Sumitomo metal industries, ltd. developed are characterized by Fe/Ni composite insert metal in Ti/ C-steel interface. These composite insert type-rolled titanium clad plates have better bonding strength than single (Fe) insert type-rolled clad plates and explosion bonded clad plates specially after heat treated condition. This excellent bonding characteristic is carried out by minimizing TiC precipitation in Fe/Ti interface where Ni insert hinders C deffusion from C-steel through Fe insert.
This paper presents these characteristics on bonding strength and the latest experiences on forming of rolled titanium clad and design data, especially relationship between drawing ratio and clad plate thickness in head forming and fatigue test results on T fillet welded joint.
Sumitomo metal industries, ltd. has already applied these titanium clad steel plates to various plants such as power plant condenser (tube sheets), pulp and paper industries (bleaching towers) and some chemical plant vessels, etc.
