Dillimax S690QL1 is a high strength fine grained quenched and tempered structural steel. It has a minimum yield strength of 690 MPa. Known as Dillimax 690E  it is extra tough with minimum impact values down to -60 oC. We specialise in heavy steel and have plates available up to 250 mm in S690QL1

Dillimax S690QL1 Steel PLates Ex-Stock

S690QL1 has the steel number 1.8988 according to EN10025-6 and is available on an ex-stock basis in thicknesses from 6 mm to 250 mm. For new rolling from Dillinger Hutte thicknesses up to 200 mm are possible.

  • Thickness: Up to 250 mm
  • Width: Up to 3 metres wide
  • Length: Up to 12 metres long
  • Certificate: EN10204 3.2. Some 3.1 available)
  • Mill: Dillinger

S690QL1 Applications

S690QL1 is used for cranes, flood gates, bridges and many other applications where high strength is required with reduced weight and easy machinability. Given their high load capacity and risk reducing features S690QL1 can also reduce material and fabrication costs by 40% as a 33 mm plate of S690 can compare to a 65 mm 355 plate

The Dillimax 690E plates that we offer carefully balance the increased allow content required in the thicker plates that we stock with the requirement for a low CEV to maintain good weldability. Typically the CEV values for Dillimax steels are far below the values required by EN10025-6 meaning that in comparison to other high yield steels weldability is significantly improved. This saves significant cost and time during production

Typically the CEV (C+Mn/6+(Cr+Mo+V)/5+(Cu+Ni)/15) for 40 mm S690QL1 plate will be below 0.30 and even at 180 mm it will be below 0.35 (in EN10025-6 comparable figures at 0.65 and 0.83 respectively)

S690QL1 high strength steel plates stocked in our warehouse are all rolled by Dillinger Hutte (either in Dunkirk or Dillingen) and come with an MTC approved by an independent 3rd party assessor (EN10204 3.2)

We keep large quantities of S690QL1 in stock and are able to rapidly cut and dispatch plates to all Asian ports either on an FCA Antwerp basis for you to do your own shipping or through our experienced forwarder on a CIF basis

European customers can purchase S690QL1 plates from AncoferWaldram or order new rolling directly from Dillinger Hutte. You can purchase a copy of EN10025-6 from BSI
