Definitions

  • the present invention has as its object the provision of a method of production for producing a “less than 6.5 mass % Al content steel sheet” having an unprecedentedly high ⁇ 222 ⁇ plane integration.
  • Steel sheet having a high ⁇ 222 ⁇ plane integration comprising steel sheet having an Al content of less than 6.5 mass % on at least one surface of which a second layer is deposited and alloyed with the steel sheet, characterized by one or both of:
  • the second layer does not necessarily have to be deposited.
  • the second layer deposited on the steel sheet may therefore be removed before heat treatment.
  • the method of heat treating the sheet to alloy part or all of the second layer and produce steel sheet having a high ⁇ 222 ⁇ plane integration is also included in the present invention.
  • the matrix steel sheet was produced by four types of ingredients with different Al content.
  • the Al content was, by mass %, 7.5% (ingredients J), 6.4% (ingredients K), 3.4% (ingredients L), and 0.002% or less (ICP detection limit or less) (ingredients M).
  • C 0.083%
  • Si 0.11%
  • Mn 0.23%
  • Cr 0.002% or less
  • N 0.003
  • a balance of iron and unavoidable impurities were included in the ingredients.
  • the burr resistance was evaluated by using 10.0 mm ⁇ punch and a 10.3 mm ⁇ die for punching and measuring the burr height around the punched hole by a point micrometer.
  • the alloying ratio of the steel sheet was found as follows: At the L cross-section, in a field of the L direction 1 mm ⁇ entire thickness, the EPMA method was used to measure the plane distribution of the Fe content and the plane distribution of the content of the deposited metal elements among Mo, Cr, Ge, Si, Ti, W, and V.
  • Ge metal was deposited as the second layer.
  • the ⁇ 222 ⁇ plane integration and the ⁇ 200 ⁇ plane integration were both in the range of the present invention.
  • the burr height was 8 to 9 ⁇ m or much lower than the comparative examples.
