PURPOSE:To produce a titanium clad steel plate having high joining strength and bending workability by sandwiching a clad steel plate interposed with an intermediate joining material of specific metal between titanium and steel and further between base material of steel and cladding material of titanium. CONSTITUTION:A titanium plate 1, an intermediate joining material 2 and a steel plate 3 are joined by a conventional known explosive cladding method. Here, the material 2 is any one among niobium, niobium alloys, tantalum and tantalum alloys. The 3-layered clad steel 5 joined in such a way is hot-rolled, whereby a sheet of the 3-layered clad steel 5 is obtained. Said layer 5 is interposed as an intermediate layer between cladding material of titanium 6 and base material of steel 7, and the titanium plate 1' of the plate 5 and the titanium 6 as well as the plate 3' and the steel 7 are joined respectively by a known explosive welding method or a diffusion welding method. Such clad steel 8 is hot- rolled, whereby the thicknesses of the respective layers are changed respectively (1'', 2'', 3'', 5', 6', 7'). |
