Download data sheet

General Product Description

Strenx 1300 E/F is an ultra-high-strength structural steel with a minimum yield strength of 1300 MPa. Typical applications include load-carrying structures that place very high demands on low weight. SSAB developed Strenx 1300 E/F for building the lightest possible steel solutions or providing an alternative to other materials. 

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 1300 E/F is available in plate thicknesses of 4.0 – 15.0 mm. Strenx 1300 is available in widths up to 2900 mm and lengths up to 14630 mm depending on thickness. More detailed information on dimensions is provided in the dimension program.

Delivery Conditions

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

Delivery requirements can be found in SSAB’s brochure Strenx® Guarantees or on 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, [email protected].

Strenx® 1300 E/F has bending guarantees according to Strenx® Bending Guarantees Class D. Strenx 1300 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.
