STANDARD STEEL GRADES FOR COLD HEADING

We have a wide range of cold heading grades, all from simple to high demanding applications. Thanks to our tight chemistries we supply equal properties delivery after delivery.

See our product leaflet for cold heading wire where we show some of our standard grades. We can also supply customized grades to your unique requirements:

Wire, Cold Heading

IMPORTANT PROPERTIES FOR COLD HEADING

To get best possible properties for cold heading, following parameters are important:

  • Tight chemistry for identical properties
  • Mechanical properties and deformation hardening
  • Corrosion properties
  • Surfaces and lubricants
  • Dimension tolerances

CONDITIONS, SURFACES AND LUBRICANTS

Different end treatments of wire rod combined with various processes during the drawing operations, we can reach the surface smoothness needed for different applications. Our wire is supplied in annealed or adjust drawn conditions. With our collection of lubricants we can adjust the wire to customers requirements regarding tool wear, product geometries etc:

Stearate
FAGERSTA XFK-coating (Na and K based)
FAGERSTA XFT-coating (Synthetic)
FAGERSTA XFN-coating (Na based)
FAGERSTA XF-coating (Synthetic and Ca based)

Oil / Grease
FAGERSTA XFO-coating (Oil)
FAGERSTA XFH-coating (Grease)
