General Product Description

Strenx® 1300 E/F is an ultra-high-strength structural steel with a minimum yield strength of 188 ksi.

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.

Strenx® 1300 E/F 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 0.157" – 0.591". Strenx® 1300 E/F is available in widths up to 114.173" and lengths up to 575.983" depending on thickness. More detailed information on dimensions is provided in the dimension program.

                  Welding, bending and machining

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

                  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 392ºF. 

                  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.
