一、奥氏体不锈钢的特点奥氏体不锈钢的标准组成是18％Cr、8％Ni。一般叫做18-8不锈钢。以它做基准,根据使用目的变化C、Ni、Cr的含量,或添加Ti、Nb等元素,便可产生其它奥氏体不锈钢,例如:1Cr18、Ni9Ti、0Cr18Ni10Ti、1Cr18Ni11N_b等。其化学成分如表1,用这些不锈钢做弹性元件波纹管,与黄铜、磷铜等波纹管相比,具有耐高温,高压和耐蚀等特点。因此奥氏体不锈钢波纹管的应用越来越多。图1是18％Cr+Ni及8％Ni+Cr的断
First, the characteristics of austenitic stainless steel The standard composition of austenitic stainless steel is 18% Cr, 8% Ni. Usually called 18-8 stainless steel. Use it as a benchmark, according to the purpose of change C, Ni, Cr content, or add Ti, Nb and other elements, can produce other austenitic stainless steel, such as: 1Cr18, Ni9Ti, 0Cr18Ni10Ti, 1Cr18Ni11N_b and so on. The chemical composition shown in Table 1, with these stainless steel bellows flexible components, and brass, phosphor bronze and other bellows, with high temperature, high pressure and corrosion resistance and so on. Therefore, the application of austenitic stainless steel bellows more and more. Figure 1 shows the break of 18% Cr + Ni and 8% Ni + Cr
