化学機器には適用できないという問題がある。Then, to this clad steel made of titanium or zirconium laminated to steel, a titanium steel plate was combined by local welding with a thin copper plate sandwiched between the steel plate and the titanium plate as shown in Japanese Utility Model Publication No. 54-3159. There is Tsudo Steel. However, in this titanium-clad steel, fragile intermetallic compounds are formed at the boundary between titanium (cladding material) and steel (base material), resulting in cracks, low adhesive strength, and easy peeling. Therefore, there is a problem that it cannot be applied particularly to chemical equipment such as pressure vessels.

ニウムクラツド鋼の製造は不可能とされている。(1) The build-up welding method involves welding a cladding material onto the surface of the base metal. When the titanium or zirconium cladding material is fused with the steel base metal, the titanium and the steel bond together. Since a brittle intermetallic compound between zirconium and steel is formed, it is metallurgically impossible to manufacture titanium-clad steel or zirconium-clad steel.

製造することができる。(3) Explosive pressure welding is a method in which the cladding material and the base material are welded together in a cold manner by exploding explosives and making full use of the explosion energy. With this method, it is possible to produce a good-quality rad steel in which no intermetallic compounds are formed at the welding boundary.

ことのない優れたチタニウムクラッド鋼、ジルコニウム
クラツド鋼である。And, since the manufacturing method has the above-mentioned structure, it can be manufactured by a simpler method than the currently used titanium clad steel and zirconium clad steel by explosive welding. This is an excellent titanium-clad steel and zirconium-clad steel that has good adhesion and does not peel off, since no fragile intermetallic compounds are formed between the laminate and the base material.
