Strenx 700


A yield strength of 700 MPa and above is the
new normal when designing in high-strength steel.
If you are using a steel of lower strength, your
products are probably not living up to their potential.


Upgrading to a steel with higher yield strength leaves room for more high performing designs with increased load bearing capacity. The stresses can be higher which allows for the use of thinner steel. This adds several advantages:

  • Depending on the starting point, designers can cut up to 40 percent weight off steel structures – and still increase the fatigue life
  • If the parts are welded, welding time and the amount of welding consumables will be significantly reduced

Yield strength defines the load – or stress – the steel can take before it becomes plastically deformed. The relation between elongation and load is linear up to the yield point. This means that before reaching its yield point, the steel will return to its original shape when the load is released.

Strenx® steel has highly consistent and guaranteed bending properties for repeatable performance in the workshop.



Strenx® 700MC is commonly used in lightweight solutions for trailer chassis. Upgrading a trailer chassis from a 350-grade using Strenx® 700MC typically generates a weight reduction of about 30% for the chassis structural parts, but depending on the chassis design, the weight reduction potential may be higher; even up to 50%.

Upgrading a trailer chassis from a S355 grade steel to Strenx® 700 performance steel can typically generate weight savings of 30% and more.


Strenx® steel plates, tubes and profiles are perfect for making agriculture machines stronger and lighter, for higher productivity, reduced fuel consumption and less soil compaction.

SSAB's top tips for designing with advanced high-strength steel

How to design with advanced high-strength steel for stronger, lighter and safer steel solutions.

Think smart, and think ahead

Because plates made from advanced high-strength steel (AHSS) are less thick but subjected to higher stress levels than conventional steels, the use of this steel places an increased focus on design. The design can literally make — or break — the potential of a long-lasting product.

Modern technology makes it possible to develop new products in a shorter time. Computer-based tools have speeded the process from concept to finished product. Still, all simulations must be verified using the appropriate methods to ensure correct results.

Particularly important points to consider when using AHSS include:

  • Structural design
  • Choice of material
  • Manufacturing methods
  • Welding and other workshop techniques
