This paper investigate the characteristics important to injection moulding via rheological behaviour, injection moulding, debinding and sintering process of water and gas atomised 316L stainless steel powder using new locally based binder system; palm stearin. The critical powder loading for injection moulding were 65vol% and 62vol% for gas and water atomised respectively. The gas atomised powder proves easier to mold because of a low interparticle friction and high packing density. In contrast, the water atomised powder has high viscosity of the injection moulding feedstock, high interparticle friction and a low packing density that interfere with injection moulding. Binder debinding was performed using solvent and thermal method. After debinding the samples were sintered at 1360oC using a high temperature vacuum furnace. Results indicate that water atomised powder could be sintered to 95% of theoretical density, while gas atomised powders could be sintered to near full density.
