General Product Description

Strenx® 1100 E/F is a structural steel with a high yield strength at a minimum of 1100 MPa.

Typical applications include demanding load-bearing structures. Despite its strength, the material is surprisingly easy to weld and bend.

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® 1100 E/F is available in plate thicknesses of 4.0 – 40.0 mm. Strenx® 1100 is available in widths up to 3200 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).

Fabrication and Other Recommendations

Welding, bending and machining

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

Strenx® 1100 E/F has bending guarantees according to Strenx® Bending Guarantees Class C.

Strenx® 1100 E/F has obtained its mechanical properties by quenching, and at our discretion, subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 200ºC.

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.
