Analisa Sifat Mekanis Sambungan Las TIG Baja Grade 91 Dengan Perlakuan PWHT

Journal of Energy, Materials, & Manufacturing Technology
Grade 91 steel is a high-alloy steel widely used in power and petrochemical industries due to its resistance to high temperatures, oxidation, and corrosion. However, welding this steel requires post-weld heat treatment (PWHT) to reduce residual stresses and enhance toughness. This study analyzes the effect of varying PWHT holding times (0, 4, 8, and 12
