Characteristics of water atomized 316L powder material

   

SEM of water atomized 316L             Depth of the surface densified layer           Very smooth surface sinteredfrom fine WFP-7 316L powder material

 

Gas atomized 316L for high gloss surface application. Sintered in H_{2 and partial pressure argon respectively}

    

Microstructure of sintered 316L-G         Void size usually was 3~5μm in diameter and void ratio was at the level of 0.3~0.8%,sintered in H_{2 atmosphere             Very thick depth of the surface densified lay when sintered in partial pressure argon atmosphere}
