Abstract
The present invention provides a BA-finished stainless steel product having superior antibacterial properties and corrosion resistance and a method for producing the same. Specifically, after a stainless steel product is subjected to BA treatment, the stainless steel product is immersed in a solution containing Ag ions having a concentration of 0.0001 to 1.0 mol/l so that a BA film contains, in area percentage, 0.0002 to 0.05% of Ag particles and Ag compounds, and further, stainless steel product contains 0.001 to 0.10% by weight of Ag and optionally further contains 0.001 to 0.30% by weight of V.
