Abstract

The microstructure and mechanical properties of 0Cr21Ni6Mn9N austenitic stainless steel cold drawn pipe were investigated at various annealing temperatures. It was found that the tensile strength and the yield strength increased slightly, and then decreased with the temperature increasing from 200 to 750 °C. The highest value of tensile strength and yield strength reached 1062 and 942MPa at 600 °C, respectively. However, the elongation has an opposite trend to the tensile strength and yield strength. The microstructure evolution of the cold drawn pipe annealed at different temperatures was observed. The results indicate that when annealed below 550 °C, recovery is dominant. At 550 °C, it is recovery and partial recrystallization. Over 550 °C, complete recrystallization has likely occurred. Moreover, the Cr2N particles near the grain boundaries were found, and the amount of precipitates along the grain boundary indexed as M23C6 were increasing at 650-800 °C.
