Abstract: Austenitic, ferritic and duplex stainless steels obtained through powder metallurgy technology were sintered in vacuum. Powders were compacted at 650 or 750 MPa and sintered in vacuum with two sinter-cooling rates (furnace- and water-cooling). Mechanical properties, using tensile testing and hardness measurements were evaluated. A full microstructural study of the three types of stainless steels was performed. The mechanical behavior was a function of the sinter-cooling rate and the chemical composition. Duplex stainless steel showed the best mechanical behavior. The use of high compaction pressure and water-cooling process promoted the best mechanical results for all compositions.
