OUR DUPLEX STEEL GRADES

We have a wide range of Duplex grades for many different applications i.e. cold heading, welding and bright wire. Thanks to our tight chemistries we supply equal properties delivery after delivery.

See our product leaflet for Duplex wire rod where we show some of our standard grades:

CHARACTERISTIC PROPERTIES FOR DUPLEX STEEL

Duplex steel are often characterized by:

  • Good corrosion properties
  • Good mechanical properties
  • Good fatigue properties
  • High resistent against abrasion
  • Good welding properties

CONDITIONS

  • Direct cooling (DK)                     ASTM 10-13
  • ”In line”-annealing (DST)            ASTM 5-8
  • Pit furnace (SG)                         ASTM 3-6

Our standard procedure is to supply Duplex wire rod in direct cooled condition.

DIMENSIONS
