The warm compacting behaviors of four different kinds of stainless steel powders,304L,316L,410L and 430L,were studied. The results show that warm compaction can be applied to stainless steel powders. The green densities and strengths of compacts obtained through warm compaction are generally higher than those obtai ned through cold compaction. The compacting behaviors in warm compaction and col d compaction are similar. Under the compacting pressure of 700 MPa,the warm co mpacted densities are 0.100.22 g/cm~3 higher than the cold compacted o nes,and the green strengths are 11.5%50% higher. The optimal warm compa cting temperature is 100110 ℃. In the die wall lubricated warm compact ion,the optimum internal lubricant content is 0.2%.
