Abstract

Sensitization due to welding is one of the most common causes of intergranular corrosion in Type 304 stainless steel in service. At some distance from the weld interface, the material might be in the sensitization temperature range long enough for chromium carbides precipitation to occur at the grain boundaries. The extent of sensitization is detected, in most cases, by the oxalic acid test (ASTM A262, Procedure A). Recently however, a new method for the detection of sensitization (electrochemical potentiokinetic reactivation, EPR) has been proposed. The purpose of this note is to compare the relative merits of these two methods (ASTM A262 and EPR) in the detection of sensitization in Type 304 stainless steels welded by the homopolar resistance welding (HPRW) process.
