Abstract

316 L steel specimens, wt %, (18 Cr - 8 Ni - 2 Mo) containing nitrogen in the range of 0.02 - 0.6 wt% in powder form, were solution treated at 1100°C for 30 min. followed by water quenching. Solution treated materials were subjected to aging at temperatures of 700 and 800°C for several intervals of time. X-ray diffraction and Scanning electron microscopy were used to study the morphology of the precipitates at different aging conditions. The hardness of these materials was determined. The morphology and size of the precipitates produced during aging were observed to depend on the aging parameters (time and temperature) and nitrogen content.
