Abstract (en)
[origin: DE10359679B3] Fixing screw formed by cold rolling consists of a material made from steel having a ferritic structure and further components having a higher carbon content compared with the carbon in the ferrite. The mixed structure has a carbon content of maximum 0.42 wt. % and a maximum grain size corresponding to at least 2000 grains/mm 2>, preferably 3000 grains/mm 2>, with inherent stresses maintained by he cold rolling.
