    • Abstract
  • The present paper studies processes for producing porous stainless steel tubes by rolling stainless steel powder and followed by sintering, winding, welding, etc.The gas atomized stainless steel shots having a particle size over 5mm were crushed into powders of -100+250mesh by Eddy rotary mill. The thickness of stainless steel tube was 0.8-1.2mm. The average diameter of the pores of porous stainless steel tubes was 6 to 15μm. The relative permeability of the porous stainless steel tube for nitrogen was (3~7)×10-3L·N/cm2·min·mmH2O.
