Processing and Properties of 18Ni Maraging Steel by Powder Metallurgy

Abstract

Using 18Ni Mar 300 powder processed by the rotating electrode process, rods were extruded under varying temperatures and ram speeds. It is observed that control of both variables allows structure control and increases the Charpy V-notch toughness from 7 to 23 ft-lb at room temperature.
