Amstrong® Ultra 690 QL – QL1

Advantages
  • Weight saving: Thanks to its minimum yield strength of 690 MPa, it enables to save weight in the final structure.
  • Easy forming and weldability: Thanks to its exceptional purity rate (very low sulphur and phosphorus contents), and its adapted chemical analysis, Amstrong® Ultra 690 is easy to shape and weld, even for heavy and thick plates. The reduced carbon and alloying elements content of Amstrong® Ultra 690 allows welding in very good conditions with excellent characteristics.

Amstrong® Ultra 890

Advantages
  • Weight saving: Thanks to its minimum yield strength of 890 MPa, Amstrong® Ultra 890 enables large weight savings or support higher stresses and thus carry higher payloads.
  • Ease in fabrication: With a special steel making process, and an adapted chemical analysis (low alloying content), Amstrong® Ultra 890 is easy to machine, bend and weld which simplifies production and maintenance.
  • Cost efficiency: By using Amstrong® Ultra 890 and thus thinner plates in welded structures, you limit preheating conditions, you decrease quantities of consumables, welding time and thus production costs.

Amstrong® Ultra 960

Advantages
  • Amstrong® Ultra 960 is a quenched and tempered steel for structure with very high strength.
  • Weight saving: Thanks to its minimum yield strength of 960 MPa, Amstrong® Ultra 960 enables large weight savings or support higher stresses and thus carry higher payloads.
  • Cost efficiency: By using Amstrong® Ultra 960 and thus thinner plates in welded structures, you limit preheating conditions, you decrease quantities of consumables, welding time and thus production costs.
