南非比勒陀利亚的工业科学技术研究所采用电化学方法研究了氮和镍的含量对Fe— 17% Cr— 15 % Mn为基础的不锈钢耐腐蚀性能的影响 ,氮的含量在 0～ 0 .4%变化 ,镍的含量在 0～ 4%变化 ,并研究了既不含氮也不含镍 ,以及只含 0 .35 %氮的情况。同时还研究了添加 1%的铜对这种不锈 The Institute of Industrial Science and Technology in Pretoria, South Africa, investigated the effect of nitrogen and nickel contents on the corrosion resistance of stainless steels based on Fe-17% Cr-15% Mn by electrochemical methods. The nitrogen content is between 0 and 0 .4%, the nickel content varies from 0 to 4%, and the case of neither nitrogen nor nickel and only 0.35% nitrogen has been studied. Also studied adding 1% copper on this stainless steel
