PROBLEM TO BE SOLVED: To provide a stainless steel material having excellent corrosion resistance, antibacterial property, and durability, and having excellent antibacterial property even after being subjected to a currently widely used surface treatment including polishing, and a method for producing the same. I will provide a. SOLUTION: Silver and silver compounds are added to stainless steel in an amount of 0.001 to 0.30 wt% in terms of Ag, or V: 0.001 to 0.001%. 1.0 wt%, and one part of a silver compound in a steel material is made into a silver oxide. % Ag) wt% or less, and silver or copper antibacterial component particles are preferably permeated and fixed to the surface layer of the stainless steel material. It is preferable that a liquid containing an antibacterial component is applied to the surface of a stainless steel material, and the solution is permeated and fixed by pressing or rubbing. Silver or a silver compound is preferable as the antibacterial component. When continuously casting molten stainless steel, the casting speed of the continuous casting is preferably set to 0.8 to 1.6 m / min. |
