Mechanical Characterization of Monel 400 and 316 Stainless Steel Weldments

Dissimilar combinations of Monel 400 and austenitic stainless steel AISI 316 is widely used in the petrochemical, nuclear industries where the weldments are usually subjected to hot corrosion. This paper deals with the assessment of metallurgical and mechanical properties of these bimetallic joints obtained by Gas Tungsten Arc Welding process using ERNiCrMo-3 filler metal. A detailed structure- property relationship was made on these bimetallic joints using the combined techniques of optical microscopy, SEM/EDAX analysis.
