DUAL-PHASE STEELS

Applications

The dual phase bake - hardening steels is a versatile material for the automotive industry due to its improved formability, capacity to absorb crash energy, and ability to resist fatigue.

U. S. Steel Košice has implemented and maintains a quality control system in accordance with the standard EN ISO 9001 and IATF 16949 for the automotive industry, issued by TÜV SÜD.
