Abstract

This research presents the effects of temperature and cooling rate on mechanical
properties of powder injection molded 316L Stainless steel. Steel powder and binder were mixed
together to produce the feedstock. The green samples were produced by injection molding and
debinded. Brown test samples were sintered in vacuum at 1325ºC, 1360ºC and 1380ºC for 2h with
two heating and cooling rates 5ºC/min and 10ºC/ min. The test samples sintered at 1325ºC achieved
maximum sintered density. The higher cooling rate improved the strength of the sintered test
samples. The maximum sintered density of 96% and tensile strength of 503MPa was achieved and
these results are comparable to the wrought 316L stainless steel (according to ASTM standard).
