PURPOSE:To produce a titled clad steel having substantial joint strength at a good yield by interposing Cr, Mo, V, Ni and Cu as single or plural layers between a titanium material and a steel material and starting rolling in a specific temp. range after seal welding. CONSTITUTION:Two sheets of laminates each formed by interposing an insert material 3 consisting of single or plural layers of Cr, Mo, V, Ni and Cu between a steel plate 1 and a Ti or Ti alloy plate 2 are made into a set by interposing a release material 4. The steel plates 1, 1 and the spacer 5 are subjected to seal welding 6 to avoid supply of oxygen to the joint surfaces. The laminates are then rolled at a rolling start temp. of >=500 deg.C and <=1,000 deg.C to form a clad steel. Both ends are cut by cutting line 8 after hot rolling and cut parts 9 are separated at the release material 4 part, by which two sheets of titanium (alloy) clad steels are obtd. |
