Fulltext PDFMost power plants have employed P91 steel to construct boiler steam pipes because of its excellent mechanical qualities at elevated temperatures for more than 20 years. Nonetheless, following welding procedures, it is essential to evaluate the mechanical characteristics of P91 steel elements. P91 steel is frequently welded using a variety of techniques, such as metal inert gas welding, submerged arc welding, along with tungsten inert gas welding. The mechanical characteristics of P91 steel after welding are greatly influenced by the welding feed conditions. The influence of parameters related to welding upon the mechanical properties of P91 steel is highlighted in this paper. It also emphasizes the adjustments made to various welding processes in order to improve P91 steel's toughness, hardness, along with tensile strength. This review also identifies research gaps and potential research opportunities by performing an in-depth literature review, which might be helpful for researchers working in this area.
