已有报导,在铁素体不锈钢中添加铜(Ｃｕ)经过时效处理有εＣｕ相析出时,发现具有抗菌性能。日本日新制钢公司技术研究所等单位对奥氏体不锈钢添加Ｃｕ元素的退火材和时效材进行了抗菌性能的研究。试验材选择ＳＵＳ304ＪＩ钢的3种基本成分:Ａ钢成分(%)0.03Ｃ0.50Ｓｉ1.80Ｍｎ18.
It has been reported that addition of copper (Cu) to ferritic stainless steel after aging treatment precipitated the εCu phase and was found to have antibacterial properties. Nippon Steel Corporation, Nisshin Steel Technology Research Institute and other units of austenitic stainless steel added Cu elements of the annealed and aging materials were antibacterial properties. Test material selection SUS304JI steel three basic components: A steel composition (%) 0.03C0.50Si1.80Mn18.
