Abstract
The production of microalloyed steel coils (thickness 8 mm) of strength category K60 (X70) with requirements on the low-temperature strength is studied in industrial trials. Microalloying of the steel with 0.10% V and 0.020% N and controlled rolling in the casting and rolling system, with a final deformation temperature of 800°C, results in the production of metal with high strength (σB ≥ 600 N/mm2, σy ≥ 520 N/mm2) and plasticity (δ5 = 28%) with satisfactory strength at –40°C according to impact-flexure and drop tests.
