Title: Study on precise nitridation process of sintered 316L stainless steel
Abstract: Nitriding process of P/M 316L sintered in vacuum has been studied. The results
show that the nitrogen content in the sintered 316L is increased with an increase of nitrogen
pressure and nitriding temperature, and little increased with heat preservation time. The ni-
trogen content of the treated 316L can be controlled accurately by controlling the nitrogen
gas pressure and nitriding temperature. Bending strength and hardness of the nitrided 316L
material are improved, but its plasticity and corrosion resistance become slightly poor. The
samples containing 0. 41%N show good comprehensive properties.
