In which of the following metals does the phenomenon of ‘weld decay’ occurs? Correct Answer stainless steel

Weld decay is a form of intergranular corrosion, usually of stainless steels or certain nickel-base alloys, that occurs as the result of sensitization in the heat-affected zone during the welding operation.
