ABSTRACT:
A process for producing a metallic catalyst-carrier, comprising the steps of: preparing a steel sheet containing 9.0 to 25.0 wt % Cr and 0.01 to 6.0 wt % Al, plating the steel sheet with Ni at an amount of from 0.3 to 10.0 g/m.sup.2, then plating with Al or Al-alloy at a plated amount defined by the formula; ##EQU1## and with a provision that the thickness of an Al-Fe alloyed layer is controlled to a thickness of 10 .mu.m or less, cold rolling to a rolled thickness of 0.1 mm or less, working to a body of a required form, and heat-treating the body.
