There have been research efforts to increase the efficiency of power plants by improving creep-resistant steels having stable
mechanical properties at elevated temperatures. The components operating at temperatures between 575°C and 650°C are
usually made of P91 (9Cr-1Mo) steel. The application of welding techniques creates a risk of reduction in high-temperature
strength and creep resistance, particularly in the heat-affected zone of the weldments. In this study, the effect of the
shielded metal arc welding (SMAW) on the high temperature tensile properties of P91 type steel plates was investigated.
