<p>A cladding metal layer (1-C) consisting of at least one layer of titanium or a titanium alloy is bonded, as one body, with a base metal layer (3-C) consisting of at least one layer of carbon steel or low-alloy steel, by said cladding metal layer (1-C) and said base metal layer (3-C) both being bonded to an intermediate layer (2-C) of a metal selected from niobium, a niobium alloy, tantalum and a tantalum alloy. Such plates have an excellent interface bond strength even after heat treatment to improve the characteristics of the base metal. A supplemental intermediate layer (4-C) of copper, copper alloy, nickel or nickel alloy may be positioned between the intermediate layer (2-C) and the base metal layer (3-C) to reduce the thickness of the intermediate layer (2-C) in the finished product. The clad steel plate can be prepared from the respective layers using conventional bonding processes.</p> |
