不锈钢简介
Introduction to stainless steel
通俗地说,不锈钢就是不容易生锈的钢,实际上一部分不锈钢,既有不锈性,又有耐酸性(耐蚀性)。
Generally speaking, stainless steel is not easy to rust steel, in fact, some stainless steel, both stainless steel and acid resistance (corrosion resistance).
不锈钢的不锈性和耐蚀性是由于其表面上富铬氧化膜(钝化膜)的形成,这层膜使金属与外界的介质隔离,阻止金属被进一步腐蚀,并且还有自我修复的能力,如果一旦遭到破坏,钢中的铬会与介质中的氧重新生成钝化膜,继续起保护作用。
The rust resistance and corrosion resistance of stainless steel are due to the formation of chromium rich oxide film (passivation film) on the surface of stainless steel. This film can isolate the metal from the external medium, prevent the metal from further corrosion, and have the ability of self-healing. Once damaged, the chromium in the steel and the oxygen in the medium will regenerate the passive film and continue to play a protective role.
这种不锈性和耐蚀性是相对的。试验表明,钢在大气、水等弱介质中和硝酸等氧化性介质中,其耐蚀性随钢中铬含水量的增加而提高,当铬含量达到一定的百分比时,钢制闸门 钢坝 保定轻钢别墅 保定平面设计培训 保定室内设计培训 保定办公家具 保定空调维修 钢的耐蚀性发生突变,即从易生锈到不易生锈,从不耐蚀到耐腐蚀。不锈钢的不锈性,还与使用环境有关,不同的环境,要使用含铬量不同的不锈钢。
This rust resistance and corrosion resistance are relative. The results show that the corrosion resistance of steel increases with the increase of chromium water content in the weak medium such as atmosphere, water and nitric acid. When the chromium content reaches a certain percentage, the corrosion resistance of steel changes suddenly, that is, from easy to rust to not easy to rust, from non corrosion to corrosion resistance. Stainless steel stainless steel, but also related to the use of the environment, different environments, to use different chromium content of stainless steel.
