Hot-rolled steel sheet for non-oriented electromagnetic steel sheets

A hot-rolled steel sheet for non-oriented electrical steel sheets, the hot-rolled steel sheet comprising, by mass %:

• C:
• 0.0010% to 0.0050%;
• Si:
• 1.90% to 3.50%;
• Al:
• 0.10% to 3.00%;
• Mn:
• 0.05% to 2.00%;
• P:
• 0.100% or less;
• S:
• 0.005% or less;
• N:
• 0.0040% or less;
• B:
• 0.0060% or less;
• Sn:
• 0% to 0.50%;
• Sb:
• 0% to 0.50%;
• Cu:
• 0% to 0.50%;
• REM:
• 0% to 0.0400%;
• Ca:
• 0% to 0.0400%;
• Mg:
• 0% to 0.0400%;
• and
• a remainder including Fe and impurities,
• wherein a hardness HD of a deformed structure is Hv 220 or less at a distance of 10 mm from a sheet width direction end surface of the hot-rolled steel sheet to a sheet width direction middle portion, which corresponds to a portion ½t from a surface of the hot-rolled steel sheet in a sheet thickness direction, where “t” is a thickness of the hot-rolled steel sheet;
• and
• wherein a hardness difference HS=HD−HU between the hardness HD of the deformed structure and a hardness HU of a recrystallized structure at a distance of 10 mm from a sheet width direction end surface of the hot-rolled steel sheet to a sheet width direction middle portion, which corresponds to a portion ⅛t from the surface of the hot-rolled steel sheet is less than Hv 20.
