Wet chemical etching of stainless steel foil by aqueous ferric chloride solution was investigated in this study. Effects of various process parameters (e.g. etchant agitation rate, etchant temperature, Fe 3+ ion concentration, free HCl concentration, specific gravity, etc.) on the etch rate was first studied, and it was found that the etch rate of AK (alu- minum-killed) steel, chromium metal and stainless steel (STS430J1L alloy) follows the pseudo-first order reaction equa- tion. When the fatigue ratio of etchant was kept under 16%, sludge was not formed in the solution, and the etched surface showed smooth roughness. The etch rate decreases as Baume of etchant increases, but the effect of free HCl con- centration on the etch rate turned out to be minimal. Experimental data were compared with the calculated results from modeled equation, showing very good agreement.
