Title:
STAINLESS-STEEL SHORT FIBER, AND SINTERED POROUS BODY USING IT
Document Type and Number:
Japanese Patent JP2002226901
Kind Code:
A
Abstract:
To provide a stainless-steel short fiber in which the unevenness of an aspect ratio can be suppressed and to provide a sintered porous body in which the pore characteristics can be stabilized by using the short fibers.
The stainless-steel short fiber has a columnar shape free from round edge due to cutting at its ends, and fiber diameter (d) is made to ≤10 μm and the average value of the aspect ratio between the diameter (d) and the length (L), L/d, is made to 2-20. The aspect ratio can be reduced by regulating the amount of N in the short fiber to 0.02-0.50 wt.%.
