Abstract

A process for coating a steel strip, particularly ferritic stainless steel, with aluminum by hot quenching, in which the strip is preheated to a temperature less than 500.degree. C. in a first non-oxidizing atmosphere containing a quantity of oxygen less than 3%, the strip is then heated to a temperature less than 950.degree. C. in a second non-oxidizing atmosphere, the strip is then conveyed to an atmosphere (3, 4) which is non-reactive at the coating temperature, and, finally, the strip is quenched in a coating bath.
