Abstract
In an antibacterial stainless steel wire and its manufacturing method, a wire drawing process, a cold working process, or a solution treatment integrated with an ageing treatment are used for making a precipitation of copper into an independent phase and in a granular form uniformly distributed in a stainless steel substrate, such that the stainless steel wire has an antibacterial effect.
Claims6
A manufacturing method of an antibacterial stainless steel wire, comprising the steps of:
- performing a wire drawing process to a stainless steel with a steel type having a copper content greater than 0.8 wt % to manufacture a stainless steel wire with a required external wire diameter;
- performing a solution treatment to the stainless steel wire, wherein the solution treatment is carried out at a solution temperature of 950° C. to 1150° C.;
- and
- performing an ageing treatment of the stainless steel wire processed by the solution treatment, wherein the ageing treatment is carried out at a temperature of 600° C. to 800° C. for a processing time of 0.5 hour to 5 hours, such that a precipitation of copper contained in the stainless steel wire is in an independent phase.
A manufacturing method of an antibacterial stainless steel wire, comprising:
- performing a cold working process to a stainless steel with a steel type having a copper content greater than 0.8 wt % to form a hard wire;
- performing an ageing treatment to the hard wire, wherein the ageing treatment is carried out at a temperature of 600° C. to 800° C. for a processing time of 0.5 hour to 5 hours, such that a precipitation of copper contained in the stainless steel wire is in an independent phase;
- and
- performing a solution treatment to the hard wire processed by the ageing treatment, wherein the solution treatment is carried out at a solution temperature of 950° C. to 1150° C.
