Description

TECHNICAL FIELD

[0002] The stainless steel micro wire is an extremely fine metal wire made of stainless steel as raw material through special process, usually with a diameter less than 0.1 mm, and has the characteristics of high strength, corrosion resistance, softness and weavability. The stainless steel micro wire has the advantages of good electrical conductivity, thermal conductivity, high strength, high elasticity, wear resistance, corrosion resistance and thermal stability in oxidizing atmosphere. It is widely used in textiles and has good shielding, anti-magnetic, anti-static and anti-radiation capabilities, and its superior performance.

[0003] The stainless steel micro wire needs to be annealed during processing. The main purpose of annealing is to reduce hardness, eliminate internal stress and refine grains, so as to improve processing performance and reduce deformation risk.
