Abstract (en)
[origin: WO2021159142A1] Advanced high strength steel alloys are disclosed with a combination of toughness and a Directional Toughness Ratio (DTR). A combination of yield strength and a Tensile Squareness Ratio (TSR) can be achieved by rolling of the hot band at ambient or identified elevated temperatures.
