A work-hardened material from a stainless steel sheet, which has a chemical composition, in mass %, that C: 0.15 % or less, Si: 1.0 % or less, Mn: 1.0 % or less, S: 0.005 % or less, Cr: 10 to 20 %, Ni: 0.5 % or less, Al: 0.001 to 0.05 %,and optionally, one or more of Mo: 0.5 to 2.0 %, Cu: 0.5 to 3.0 % and Nb: 0.05 to 1.0 %, wherein Al2O3 based and/or Al2O3.MgO based inclusions having a particle diameter <= 10 mum are dispersed in a cleanness <= 0.06 %, and the material exhibits enhanced strength due to a work ferrite structure. The above work-hardened material exhibits an 0.2 % offset yield strength as high as 700 N/mm2 or higher and also is excellent in bending workability, and thus can be suitably used as parts or a structural material for a household electrical appliance, an OA equipment and the like.
