    General Product Description

    A structural steel developed for use in demanding load-bearing structures within the Offshore and Marine Industry.

    Strenx® 700 OME exceeds the requirements of S690QL, EN 10025-6. Strenx® 700 OME can be ordered with dual steel grades certificate, where the additional steel grade is defined and approved by one of the Classification Societies listed below. The dual certification offers You the benefits of excellent mechanical properties, extra tight tolerances, formability and consistency of SSAB Strenx® Guarantees.

    Classification society:

    American Bureau of Shipping AB EQ70 4.8 to 130 mm thickness
    DNV - GL NV E690, VL E690 6 to 80 mm thickness
    Lloyds Register LR EH 69 8 to 80 mm thickness

    Dimension Range

    Strenx® 700 OME is available in plate thicknesses of 4 – 130 mm and available in widths up to 3350 mm and lengths up to 14630 mm depending on thickness. More detailed information on dimensions is provided in the dimension program at www.ssab.com.

                    Fabrication and Other Recommendations

                    Welding, bending and machining

                    Recommendations are found in SSAB’s brochures at www.ssab.com or consult Tech Support.

                    Strenx® 700 OME has bending guarantees according to Strenx® Bending Guarantees Class A. Strenx® 700 OME 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 580oC. 

                    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.
