Product Description


S690 steel is a structural steel with a minimum yield strength of 690 MPa depending on thickness. It meets the requirements of EN 10025-6 for the S690 grade and thicknesses. Typical applications include demanding load-bearing structures.

S690QL steel is available in plate thicknesses of 4 – 160 mm, while S690QL1 is available in plate thicknesses of 4 – 130 mm.


Benefits include:

  • Superior bendability and surface quality
  • Weldability with excellent HAZ strength and toughness
  • Exceptional consistency within a plate guaranteed by close tolerances
  • High impact toughness which provides for good resistance to fractures


Dimension Range

S690QL is available in plate thicknesses of 4 – 160 mm and S690QL1 is available in plate thicknesses of 4 - 130 mm. Both grades are available in widths up to 3350 mm and lengths up to 14630 mm depending on thickness.

Delivery Conditions

The delivery condition is Q+T (Quenched and Tempered). The plates are delivered with sheared or thermally cut edges. Untrimmed edges after agreement.


Fabrication and Other Recommendations

Welding, bending and machining

S690QL steel and S690QL steel has obtained its mechanical properties by quenching and subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 580 ºC.

Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on this product. Grinding, especially of primer coated plates, may produce dust with a high particle concentration.
