Abstract
a method of producing steel fibres, preferably for use as concrete additive, and for the supply thereof in the production of steel fibre concrete, characterised in that to form the steel fibres (2) firstly a sheet metal strip (1) is notched either on one side or both sides, whereby steel fibre veins (4) are formed, wihich are initially still connected together by limbs (5), that further for subsequently converting the limbs (5) into thin easily mutually separable separation limbs forming separation furfaces which are fracture-rough and low in burring upo n sepration the steel fibre strip is subjected to a flexing process in which each limb (5) is subjected to multiple bending deformation about its longitudinal axis in such a way that inciplent cracks are produced in the region of the limbs (5) due to fatigue fracture and thus the separation limb is produced.

Method for producing steel product or steel component having excellent mechanical properties, steel product produced by the method and use of steel pipe made of strain hardened steel
Method for producing steel fibers that consists of notching a metal foil tape forming veins of steel fibers that connect to each other in branches or separating members separable from each other, where each branch is subjected to deformation by multiple bends around a longitudinal axis
