    General Product Description

    Strenx® 700 E/F is a structural steel with a minimum yield strength of 94-101 ksi depending on thickness. Strenx® 700 E/F meets the requirements of EN 10 025-6 for the S690 grade and thicknesses. Typical applications include demanding load-bearing structures. Strenx® 700 E (complies with S690QL) is available in plate thicknesses of 0.157" – 6.299", while Strenx® 700 F (complies with S690QL1) is available in plate thicknesses of 0.157" - 3.937".

    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

    Strenx® 700 E is available in plate thicknesses of 0.157" – 6.299" and Strenx® 700 F is available in plate thicknesses of 0.157" - 3.937". Both grades are available in widths up to 181.89" and lengths up to 575.983" depending on thickness. More detailed information on dimensions is provided in the dimension program.

            1) Unless otherwise agreed, transverse impact testing according to EN 10025-6 option 30 will apply. For thicknesses between 0.236" - 0.469", sub-size Charpy V-specimens are used. The specified minimum value is then proportrional to the cross-sectional area of the specimen compared to a full-size specimen (0.393x0.393").
