Abstract: Conversion-rolled titanium/steel bonded composite products having improved mechanical properties desirable for vessel construction are made by heating to 1,400*-1,600*F. a substantially flat metallurgically bonded titanium/steel composite of the character of composites made by explosion bonding, preferably according to the bonding process described in U.S. Pat. No. 3,397,444; commencing rolling of the composite at said temperature and continuing rolling until the thickness is no greater than one-eighth, preferably one-tenth, the prerolling thickness, the composite being roller biaxially, and the time the composite is held at 1,400*-1,600*F. not exceeding 6 hours; and heating the rolled product at 1,200*-1,300*F. for a period of at least about one-half hour.
