Abstract:

A preliminary study was made on the antibacterial behavior of a newly designed Cu-bearing type 200 stainless steel by different methods including Vickers hardness measurement, electrochemical test and antibacterial test. The results showed that Cu-rich precipitations caused by the saturated Cu in the steel matrix was not only a crucial factor for its excellent antibacterial capability, but also for its equivalent corrosion resistance as good as the commercial type 200 stainless steel.
