Ferritic Antimicrobial Stainless Steel and Manufacturing Method Thereof

摘要

The present invention relates to a ferritic stainless steel having anti-bacterial properties and a process for producing the ferritic stainless steel.;The object of the present invention is to provide an antimicrobial stainless steel which can have antimicrobial properties while maintaining the mechanical properties of ferritic stainless steel, and a method for producing the same.;In order to achieve the above object, the present invention provides a ferritic steel comprising 0.016% of C, 0.015% of N, 0.75% or less of Si, 1.0% or less of Mn, 0.04% or less of P, Of at least one of Fe and other inevitable impurities, wherein the Fe-based antimicrobial stainless steel satisfies the following conditions:-22%, Cu: 1.4-2.0%, Nb: 0.4-1.0%, Ag: 0.04-0.2% And a step of hot-rolling the steel with the above-mentioned components in a usual manner, followed by cold rolling, continuous annealing, and then maintaining the steel at a temperature of 400-650C for 0.5-2 hours and then cooling the furnace The present invention relates to a manufacturing method of an antimicrobial stainless steel sheet.
