Strenx® 700 E/F
Download data sheet
Strenx® 700 E/F is a high-strength structural steel with a minimum yield strength of 650-700 MPa depending on thickness. The steel offers superior bendability, surface quality and weldability with excellent HAZ strength and toughness. The exceptional consistency within a plate is guaranteed by close tolerances and high impact toughness provides for good resistance to fractures. Strenx® 700 E meet or exceed the requirements of the standard EN 10025-6 where Strenx® 700 E conforms to grade S690QL and Strenx® 700 F conforms to grade S690QL1. Typical applications include demanding load-bearing structures.
Strenx® 700 E is available in plate thicknesses of 4.0 – 160.0 mm and Strenx® 700 F is available in plate thicknesses of 4.0 - 130.0 mm. Both grades are 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.

1) Unless otherwise agreed, transverse impact testing according to EN 10025-6 option 30 will apply. For thicknesses between 6 - 11.9 mm, 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 (10 x 10 mm).
The steel is grain refined. *) Intentional alloying elements.

Welding, bending and machining
Recommendations are found in SSAB’s brochures at www.ssab.com or consult Tech Support.
Strenx® 700 E/F has bending guarantees according to Strenx® Bending Guarantees Class A. Strenx® 700 E/F 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.
Upgrading from Strenx® 700 E/F to Strenx® 900 E/F means you can improve the performance and reduce the weight of your equipment. The increase in yield strength by almost 30% allows for a substantial increase in the equipment’s load-bearing capacity.
