PURPOSE:To manufacture Ti clad material having excellent joinability by interposing Ni-Cr alloy material having specific composition between iron alloy material and Ti material to form raw material and hot-rolling this raw material at the specific draft after heating at the specific temperature. CONSTITUTION:The Ni-Cr alloy material containing, by weight, 32.5 -40% Cr and 55-65% Ni is interposed between the iron alloy material and the Ti material to form the raw material and this raw material is heated at 850-1010 deg.C and then, continuously hot-rolled at >=30% draft. By this method, the Ti clad material having excellent joinability can be manufactured. |
