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%.
