Machines and buildings are becoming ever larger. When you double the values of length, width and height of a component, the weight grows by a factor of 8, while the supporting cross-sectional area only grows by a factor of 4. This doubles the stress, which is calculated with the weight divided by the cross-sectional area. High-strength steels are capable of supporting these higher stresses and simultaneously lead to decreased weight of the component.
The low weight of high-strength and ultra-high-strength heavy plates saves costs: The pre-material expenses, transport charges, and the assembly and foundation costs drop drastically. Add to that the costs saved during further processing of the material. Thanks to the excellent welding properties, work can proceed quickly and efficiently. On top of this, much less filler metal is required, and the weld seam test is simplified.
We deliver high-strength heavy plates as fine-grained steels with a minimum yield strength of 620 and 700 MPa and ultra-high-strength heavy plates with a minimum yield strength of 960 MPa as special voestalpine grades.
