Influence of Post-Weld Heat Treatment on the Mechanical Properties and Microstructure of a Seamless Pipe of an ASTM A335 Gr P91 Steel

This study investigates the effects of different post-weld heat treatments (PWHT) on the mechanical properties and microstructure of ASTM 335 Gr P91 martensitic steel, commonly used in boiler applications. Mechanical tests were conducted at room temperature, 300°C, and 600°C. Two PWHT conditions wer...
