Higher strength steel, especially reinforcing steel or drawing shop feed stock with improved material properties and improved processability |
摘要 |
An elongated steel element of enhanced strength suitable for use as reinforcement for concrete or drawing feed stock has a cross section which is heterogenous in structure and strength, the cross section comprising a core, a peripheral layer and a transition region between the core and the peripheral layer, the transition region consisting essentially of higher strength, harder martensite, the peripheral layer being of lower strength than the transition region and the core being of lower strength than the peripheral layer.
