Abstract
Electrical resistance characteristics of sintered material made by stainless steel fiber has heat-resistance, and corrosion-resistance, and are therefore often used for polymer filter, automobile exhaust filters, and other filters.
In this study, 20Cr-5Al stainless fibers are.sintered for the first time by the hot water soluble resin coated coilshaving methods and electrical resistance characteristics as sintered material were studied. Though the fiber heatresistance of this stainless steel fibers has been verified, there are almost no studies on the sintering characteristics, purposes, etc. of metal fibers.
The electrical resistance characteristics of fiber sintered materials were investigated for the use in heaters, and the results showed that the specific gravity changes in the sintering, compression of rolling processes, and the specific resistance decreases as the porosity becomes decrease, indicating that the specific resistance of sintered material can be controlled.
