Abstract
Un producto de acero o una tira delgada fundida de acero que comprende en peso, menos del 0,25% de carbono, entre 0,20 y 2,0% de manganeso, entre 0,05 y 0,5% de silicio, menos del 0,01% de aluminio, y al menos uno de niobio entre 0,01% y 0,20% y vanadio entre 0,01% y 0,20%, y que tiene una micro estructura en su mayoría comprendida de ferrita acicular y bainita y más del 70% de niobio y /o vanadio en solución sólida. El producto de acero puede tener un incremento en la elongación y un incremento en el límite de resistencia después del templado por precipitación. El producto de acero templado por precipitación puede tener partículas de carbonitruro de niobio, menos del 0,25% de carbono, con un tamaño medio de partícula de 10 nanómetros y menos, y puede no tener sustancialmente partículas de carbonitruro de niobio mayores de 50 nanómetros. El producto de acero puede tener un límite de resistencia de al menos 380 MPa o una resistencia a la tracción de al menos 410 MPa, o ambos. El producto de acero o la tira delgada de acero fundido puede tener una elongación total de al menos 6% o 10%.A steel product or a thin cast steel strip comprising by weight, less than 0.25% carbon, between 0.20 and 2.0% manganese, between 0.05 and 0.5% silicon, less 0.01% aluminum, and at least one of niobium between 0.01% and 0.20% and vanadium between 0.01% and 0.20%, and which has a microstructure mostly comprised of acicular ferrite and bainite and more than 70% of niobium and / or vanadium in solid solution. The steel product may have an increase in elongation and an increase in the resistance limit after tempering by precipitation. The precipitation hardened steel product may have niobium carbonitride particles, less than 0.25% carbon, with an average particle size of 10 nanometers and less, and may not substantially have niobium carbonitride particles larger than 50 nanometers . The steel product may have a resistance limit of at least 380 MPa or a tensile strength of at least 410 MPa, or both. The steel product or the thin strip of molten steel can have a total elongation of at least 6% or 10%.
