General Product Description
Strenx® 900 E/F is a structural steel with a minimum yield strength of 830-900 MPa depending on thickness.
Strenx® 900 E fulfills the requirements for S890QL in EN 10025-6 and Strenx® 900 F for S890QL1. Typical applications include demanding load-bearing structures.
Strenx® 900 E/F benefits include:
- High impact toughness which provides for good resistance to fractures
- Superior bendability and surface quality
- Weldability with excellent HAZ strength and toughness
- Exceptional consistency within a plate guaranteed by close tolerances

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).

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.
Bending guarantees for Strenx® 900 E/F are according to Strenx® Bending Guarantee Class B.
Strenx® 900 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 550ºC.
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.
