Abstract Corrosion behaviour of type 310S stainless steel (310S) was investigated under cathodic polarisation in a chloride–bromide melt at 923 K to confirm the feasibility of cathodic protection. Potentiostatic cathodic polarisation was carried out at different potentials for 48–144 h. Mass loss after 48 h of corrosion was 1.32 mg·cm −2 without cathodic protection. This mass loss can be reduced by one order of magnitude on cathodic polarisation of 0.86 V. On this extent of cathodic polarisation, Cr-dissolution was largely suppressed. For carbon steel, a similar reduction in mass loss was observed just by 0.35 V of cathodic polarisation.
