Abstract

PURPOSE:To enhance joining strength and to efficiently manufacture clad steel by heating the joining face to the specified temperature to carry out brushing, then, sticking a Ni sheet and a stainless steel sheet together, carrying out warm rolling and joining thereon at the specified temperature and then, carrying out post-treatment. CONSTITUTION:One joining face at least of the Ni sheet 10 and the stainless steel sheet 12 is activated by heating at <=400 deg.C and degreasing and the joining interface is brushed by brushes 20. These are rolled at 50-400 deg.C at the warm rolling stage 22. It is desirable to use the pure Ni sheet annealed at >=900 deg.C as the Ni sheet. After warm rolling, these are subjected to heat treatment at the post-heat treatment stage 26 and rolled at the cold rolling stage 28 and subjected to heat treatment at the finishing heat treatment stage 30 to form a product. The joining strength is improved and clad steel can be efficiently manufactured at a low cost.
