Mechanical properties
Steel fiber combines flexibility of a traditional textile fiber with high temperature resistance of steel. Stainless steel fibers are also resistant to mechanical stresses, in particular to shearing stress, contrary to glass, ceramic or carbon fibers, and resistant to corrosion. Steel fibers are obtained by successive wire bundle-drawings [1]. Annealed wire, which is commonly specified for sizes over 0.75 mm, in the 3xx series commonly has a tensile strength of 655 to 860 MPa and an elongation (in 50 mm) of 35 to 60% [2]. Austenitic stainless steel has a typical Young´s modulus of 193 GPa [3]. Fracture of metallic filaments differs in many respects from fracture of bulk samples. Particular fabrication processes, such as drawing, melt spinning or crystallization from the vapor phase for fibers, that are needed to obtain their small lateral dimensions, may introduce specific defects and textures, and have influence on the fracture behavior [4].
