Thermomechanically Rolled Fine-Grain Steels
We deliver standard and higher strength thermomechanically rolled fine-grain steels with minimum yield strength of 355 - 550 MPa. These steels combine excellent toughness with best weldability and formabilty.
voestalpine special grade alform® M is used in bridgebuilding, high pressure pipes, vehicles and crane manufacturing.
Advantages
Our thermomechanically rolled fine-grain steels show excellent toughness and best weldability. High resistance against cold cracks and high toughness in the heat affected zone (HAZ) result in good reliability of the welded joint.
Utilization of higher yield strength of higher-strength fine-grain steels (S420, S460, alform 500 M) compared to conventional S355 results in smaller cross section of steel constructions. That leads to cost savings due to smaller component weight and therefore savings in transport, assembling and foundations as well as savings in processing, esp. in welding.
