Heat treatment effect on structure and mechanical properties of gas metal arc-welded pearlitic steel
摘要
The paper studies the heat treatment effect on the structure and mechanical properties of gas metal arc-welded heat-resistant steel walls obtained by coldArc welding. The specimens are tempered at 600 and 900 °C. It is found that 900 °C tempering leads to a complete recrystallization of the structure, higher ductility, and lower strength. High-temperature tests are carried out at 550 °C.
