Abstract

La presente invención proporciona una chapa de acero inoxidable ferrítico la cual tiene una tenacidad más excelente y excelente resistencia a la corrosión y un método para fabricar la misma. Una chapa de acero inoxidable ferrítico tiene una composición que contiene C: de 0.001 a 0.020%, Si: de 0.05 a 0.35%, Mn: de 0.05 a 1.00%, P: 0.04% o menos, S: 0.01% o menos, Al: de 0.001 a 0.300%, Cr: de 10.0 a 13.0%, Ni: de 0.75 a 1.50%, Ti: de 0.05 a 0.35% y N: de 0.001 a 0.020%, con el resto siendo Fe e impurezas inevitables, en el cual ?I [%] representada por la fórmula (1) más adelante es 65% o más y una estructura metálica tiene un tamaño promedio de grano de cristal de 45 µm o menos: 10 ?I [%] = 24Ni + 12Mn + 6Cu - 18Si - 12Cr - 12Mo + 188 (1), donde Ni, Mn, Cu, Si, Cr y Mo representan el contenido de los elementos respectivos (porcentaje en masa) y un elemento no contenido representa 0. La chapa de acero inoxidable ferrítico se fabrica sometiendo una losa de acero que tiene la composición para laminación en caliente y efectuando el recocido de la chapa laminada en caliente de 750 a 1,050°C.The present invention provides a ferritic stainless steel sheet which has more excellent toughness and excellent corrosion resistance and a method for manufacturing the same. A ferritic stainless steel sheet has a composition containing C: 0.001 to 0.020%, Si: 0.05 to 0.35%, Mn: 0.05 to 1.00%, P: 0.04% or less, S: 0.01% or less, Al : from 0.001 to 0.300%, Cr: from 10.0 to 13.0%, Ni: from 0.75 to 1.50%, Ti: from 0.05 to 0.35% and N: from 0.001 to 0.020%, with the remainder being Fe and unavoidable impurities, in the which ?I [%] represented by formula (1) below is 65% or more and a metal structure has an average crystal grain size of 45 µm or less: 10 ?I [%] = 24Ni + 12Mn + 6Cu - 18Si - 12Cr - 12Mo + 188 (1), where Ni, Mn, Cu, Si, Cr and Mo represent the content of the respective elements (percent by mass) and an uncontained element represents 0. Ferritic stainless steel sheet It is manufactured by subjecting a steel slab having the composition to hot rolling and annealing the hot rolled sheet at 750 to 1,050°C.
