Hot Tensile Properties of SMA Welded Similar and Dissimilar Joint of P91 and SS304 Grade Steels
Main Article Content
Abstract
P91 martensitic and SS304 austenitic stainless steel is identified as the steels for use in high temperature areas of ultra-super critical boilers. The boiler piping involves similar and dissimilar weld joints of P91 and SS304 grade steels. The welded joints are exposed to high temperature in service and it is therefore required to evaluate the high temperature behaviour of such joints. Hot tensile test is a short-term high temperature test which is a useful tool to study the high temperature behaviour of the welds. In this investigation, shielded metal arc welded (SMAW) similar joints of P91/P91 martensitic steel, SS304/SS304 austenitic steels joined using matching weld metal and dissimilar joints of P91/SS304 welded using Inconel weld metal are subjected to hot tensile test at temperatures of 550 deg C, 600 deg C and 650 deg C. The stress-strain behaviour of the weld joints at elevated temperature was studied.
