Cold-heading wire for manufacture of fasteners is used in many fields and in extremely varying applications. Examples are the transport, building, chemical, electronics/computer and white goods sectors.
Product properties.
Optimum cold-heading properties place high demands on a controlled manufacturing of the wire. Surfaces free from defects, steel grades adapted to the product, tight compositional limits, low inclusion and impurity contents, correct mechanical properties, correct work-hardening rate, even adapted surface coatings and tight size tolerances are examples of important parameters. |
