Abstract

With the development of metal joining technology there is a problem where there is a residual stress that is generated after connection with welding technology. This study aims to determine the basic constituent elements of austenitic stainless steel and to know the differences in tensile strength and microstructure in welding austenitic stainless steels before and after post welding heat treatment. Using austenitic stainless steel AISI 304H and SMAW welding with AWS A5.4 E308 electrodes. Single V butt joint with 70o angle. Post welding heat treatment on specimens with temperatures of 500 oC, 750 oC and 1000 oC. The results of the chemical composition test showed that the constituent elements of the austenitic stainless steel AISI 304H were Fe = 70.45%, Cr = 18.56%, Ni = 8.446% and Mn = 1,615%. The microstructure test found that the higher the PWHT temperature, the wider the ferrite phase on the base metal widened regularly, the HAZ area widened irregularly, the weld zone was widened and thin. Tensile test results before PWHT (625 MPa), PWHT 500 oC (640 MPa), PWHT 750 oC (650 MPa) and PWHT 1000 oC (590 MPa) where the PWHT 500 oC and 750 oC experience an increase in tensile stress values due to discharge residual stress, after PWHT 1000 oC the tensile stress value has decreased due to changes in the microstructure of the weld area.
