Stainless steel fibers

Chemical properties

Metal fibers combines flexibility of traditional fibers with high temprature resistance. They are also used for their thermal and electric conductivity as much as their corrosion resistance.

Metal fibers are obtained by successive wire bundle-drawings. They can be crimped or not at the end of this step.

CREAFIBRES mainly uses AISI 316 alloy, which is composed of : 

 

Carbon

C

Silicium

Si

 Physical properties

Fineness of stainless steel fibers is expressed by the diameter of an unit fiber stated in micron.

Fiber diameter is usually included between 6 and 30 microns.

CREAFIBRES mainly uses 8, 12 and 22 µm fibers as standard of working.

Stainless steel fibers are also distinguishable from other traditional fibers by its relative density.

Stainless steel fibers are around 5 times more dense than other synthetic or natural fibers: 

 

Cotton

Wool

Polyester

Méta-aramid

This measure is important to get the equivalence with the diameter of a classic yarn stated in Tex or Metric Count (Nm).

For instance, a stainless steel yarn Nm 11/2 or 182 Tex is seemingly equivalent to a yarn of (182*1,5)/7,95 = 34,4 Tex of cotton ie. a yarn of Nm 60/2.

Stainless steel fibers are also :

  • Austenic steel with a cutting resistance (contrary to glass, ceramics or carbon fibers), corrosion resistance, chemical resistance and ductility similar to copper material.
  • Melting point : 1380 °C
  • Magnetism during work hardening
  • Washing resistance.
