Abstract
A cold-rolled steel strip having an electrodeposited nickel coating exhibiting a great diffusion depth, and a process for producing this strip. In order to develop a cold-rolled strip that can be produced economically, and which has a reduced tendency to stick, good deformability, deep coating diffusion, advantageous corrosion dehavior, and improved electrochemical behavior, and in order to develop a process for producing this strip, the thickness of the nickel coating should carry a coating of cobalt which has been electrodeposited to a thickness of 0.01 to 1.0 [m, and after having been coated, the cold-rolled strip should be subjected to a final heat treatment at a temperature of between 580.degree. and 710.degree.
