Indonesia Power Unit Pembangkit Semarang}, year={2018}, url={http://156.67.221.169/410/}, abstract={In PLTGU there is an important component, namely HRSG, where HRSG is to heat water by using exhaust gas heat from the gas turbine to produce steam with a certain constant pressure and temperature, where in the HRSG there is a LP superheater which has a pressure of 11 bar and a temperature of 318 Âșc where leakage or tube changes often occur so this study aims to determine the properties of the superheater LP tube material by conducting a testing activity on the material of the Superheater LP tube that has not been damaged in order to identify the material of the tube material. These tests include metallographic testing, chemical composition testing and hardness testing in order to find out the properties of materials compared to SA 106 material standards. Grade A is suitable or not in accordance with the material standards.} }
