High strength steels

Industeel offers a complete range of high strength steel plates including all the main grades commonly found on the market (690, 890, 960 and 1100 MPa).
The quenched and tempered steel combines high yield strength and toughness and are used for the construction of stationary and mobile equipment subjected to heavy loads.

Amstrong® Ultra is a range of quenched and tempered steel plates combining high yield strength (500 to 1100 MPa) and excellent toughness.

They are generally used to build stationary or mobile equipment subjected to very heavy loads.

Due to their higher minimum yield  strengths of 690 – 890 – 960 – 1100 MPa compared to classical structural steels, Amstrong® Ultra grades enable to :

  • Reduce thickness of welded structures and make weight saving (so to limit preheating conditions, decrease quantity of welding consumable, welding time and production costs)
  • Support higher stresses and realize more resistant and innovative structures
  • Increase payload of mobile cranes
  • Reduce fuel consumption

Dimensional range:
Industeel can manufacture the largest range of thicknesses and unit weights available on the market in Quenched and Tempered (Q+T) steel grades.

  • Thickness : from 5 to 300 mm
  • Length : up to 17 meters
  • Weight : up to 80 t

The technical know-how acquired by Industeel puts us in a position to optimize our products for each application. The result is a high-end range of steel products for the world market and the capacity to find innovative solutions to new problems you may encounter.
