Abstract : The minimum potential required for complete cathodic protection has been determined for BIS 812 EMA steel which is being used for the main pressure hull of the Royal Australian Navy's Collins class submarine. The experimental method provided plots of weight loss versus applied potential for both BIS 812 EMA steel and the traditional HY80 steel over appropriate potential ranges. These were decided from determinations of the corrosion potentials of the two steels. The minimum protective potential determined was -740 mV, compared with -710 mV for HY80 and -790 mV previously determined for mild steel. (MM)
