Abstract:
A steel sheet for hot-pressing includes a specific chemical component composition. In the steel sheet, an average equivalent-circle diameter of a Ti-containing precipitate having an equivalent-circle diameter of 30 nm or less among Ti-containing precipitates contained in the steel sheet is 3 nm or more. A precipitated Ti amount and a total Ti amount in the steel satisfy the relationship of: Precipitated Ti amount (mass %)−3.4[N]≥0.5×[(total Ti amount (mass %))−3.4[N]], in which [N] indicates the content (mass %) of N in the steel. A ferrite fraction in the metal microstructure of the steel sheet is 30 area % or more.

Claim (Index 7):
A press-formed article of a steel sheet, the article comprising:\n a first region having a metal microstructure including retained austenite: from 3 to 20 area % and martensite: 80 area % or more; and a second region having a metal microstructure including retained austenite: from 3 to 20 area %, ferrite: from 30 to 80 area %, bainitic ferrite: more than 0 area % and less than 30 area %, and martensite: more than 0 area % and 31 area % or less, wherein a carbon amount in the retained austenite is 0.50% or more; and the steel sheet comprises: in mass %,\n C: from 0.15 to 0.5%, \n Si: from 0.2 to 3%, \n Mn: from 0.5 to 3%, \n P: more than 0% and 0.05% or less, \n S: more than 0% and 0.05% or less, \n Al: from 0.01 to 1%, \n B: from 0.0002 to 0.01%, \n Ti: from 3.4[N]+0.02% to 3.4[N]+0.1%, wherein [N] represents a content in mass % of N, \n N: from 0.001 to 0.01%, and \n iron.
