We supply thermomechanically rolled heavy plates made of fine-grained steels with minimum yield strengths ranging from 355 to 550 MPa with exceptional toughness and the best welding and forming properties.
As a special high-quality voestalpine grade, alform® steels are found in structural steel work, bridges, pressure pipes and in vehicle and crane manufacturing.
Our thermomechanically rolled fine-grained steels are characterized by a high degree of toughness and excellent weldability. The low degree of cold cracking and high degree of toughness in the welding seam lead to a high degree of safety in welded structures.
Utilization of the higher yield strength in the high-strength fine-grained steels (alform plate 420 M, 460M, 500 M und 550 M), as opposed to the conventional S355, results in thinner cross sections that lead to cost savings through light-weight components and thus to less expensive transportation, assembly and foundations. Savings are also achieved in component manufacturing, particularly in welding.
