Amstrong® Ultra high strength steels

Technical information

Amstrong® Ultra high strength steel grades are low alloy steel grades that complete the Amstrong® range and offer exceptionally high yield strength values.

Due to their typical low carbon equivalent value (PCM < 0.25), Amstrong® Ultra grades do not need to be pre- or post-heated when welding. They are not prone to excessive hardening due to their low carbon and low alloy content, are totally insensitive to cold cracking, and are suitable for all types of arc welding.

Available in Amstrong® Ultra 650MC to 960 MCL and 690 to 1100, these ultra high strength steel grades meet or exceed the requirements of applicable European standards. They are available as thermomechanically rolled cut-to-length sheets or as quenched and tempered sheets and quarto plates.

Further properties include:

  • Excellent formability, ductility, and bendability
  • Toughness at low temperatures
  • Fatigue resistance
  • Available in widths exceeding 2000 mm
  • Available in the fullest and widest dimensional range on the market: from 650 to 1100 MPa
  • Suitable for oxygen, plasma, and laser cutting

Amstrong® Ultra 650MC and 700MC grades meet the requirements of EN 10149-2.

The smartest choice

Amstrong® Ultra is ArcelorMittal’s range of superior ultra high strength steels with the widest dimensional and product range on the market. They combine excellent formability with toughness at low temperatures and fatigue resistance.

These grades are an excellent alternative to conventional structural steels in the 350 MPa yield strength range, enabling manufacturers to reduce steel thickness and weight. With the significant weight reduction that Amstrong® Ultra brings, you can go thinner, go higher, and go wider - making it the smartest choice.

Replacing traditional structural steels with Amstrong® Ultra grades provides significant material cost savings while maintaining good fabrication properties such as formability and weldability.

Applications in construction include:

  • Profiling: racking systems, shelving
  • Street lighting poles
  • Lifting and handling equipment
  • Goods lifts
