STEEL SHEET FOR HOT PRESSING USE, METHOD FOR PRODUCING SAME, AND HOT PRESS STEEL SHEET MEMBER

摘要

A steel sheet for hot stamping includes a predetermined chemical composition containing: C: 0.08% or more and less than 0.20%; Si: 0.003% to 0.2%; Mn: 1.6% to 3.5%, and others, and further includes a steel structure expressed by, in an area ratio: bainite: 1% to 95%; ferrite: 5% to 94%; and balance: one or more selected from the group consisting of pearlite, martensite and retained austenite. When an Mn content is represented by [Mn], a C content is represented by [C], an expression of "[Mn] + 6.67 × [C] - 2.73 ‰¥ 0" is satisfied.
