Cyclic air oxidation studies on bimetallic combinations of AISI 4140 and AISI 316Published in
2013
Volume: 16
High temperature corrosion is one of the serious, vulnerable problems in the power generation and petrochemical industries. The bimetallic joints of AISI 4140 and AISI 316 is widely used in the aforementioned areas where the greater attention is required to overcome the problems associated with hot corrosion. This paper investigates the hot corrosion behaviour of AISI 4140 and AISI 316 weldments. These dissimilar metals were welded using Gas Tungsten Arc Welding (GTAW) and Pulsed Current Gas Tungsten Arc Welding (PCGTAW) employing ER309L filler wire. Cyclic air oxidation studies were performed on the various coupons of the weldments at 600 C. The hot corroded products were revealed using the SEM/EDAX analysis. © 2013 University of Manchester and the authors.
