    摘要: The present invention provides a stainless steel being excellent in workability, corrosion resistance and antibacterial property. To be more specific, a stainless steel containing 10 wt % or more of Cr is rendered to contain 0.0001-1 wt % of Ag, or further one or more members selected from Sn: 0.0002-0.02 wt %, Zn: 0.0002-0.02 wt %, Pt: 0.0002-0.01 wt %, and, in addition, is rendered to dispersedly contain a total of 0.001 % or more in an area percentage of one or more members of a silver particle, a silver oxide and a silver sulphide each having a mean grain diameter of 500 &mgr;m or less. To disperse the silver particle, silver oxide and silver sulphide uniformly, the casting rate of continuous casting is preferably controlled to range from 0.8 to 1.6 m/min.
