Abstract
A titanium-clad steel and a method for its manufacture are disclosed. The titanium-clad steel comprises a steel base metal, a nickel insert which is bonded to the steel base metal, a low-carbon ferrous metal insert which contains at most 0.01 weight % of carbon and which is bonded to the nickel insert, and cladding of a titanium-based metal which is bonded to the low-carbon ferrous metal insert. A manufacturing method therefor comprises preparing a 4-layer clad assembly comprising the above materials, sealing the outer seams of the clad assembly by shielded arc welding, performing degassing treatment on at least the confronting surfaces of the inserts, heating the clad assembly to a temperature of 500.degree.-1050.degree. C., and performing hot rolling. The resulting titanium-clad steel has a high bonding strength.
