不锈钢板一般是不锈钢板和耐酸钢板的总称。不锈钢板是指耐大气、蒸汽和水等弱介质腐蚀的钢板,而耐酸钢板则是指耐酸、碱、盐等化学浸蚀性介质腐蚀的钢板。
Stainless steel plate is generally stainless steel plate and acid resistant steel floorboard. Stainless steel plate refers to the atmosphere, steam and water and other weak medium corrosion of steel plate, and acid resistant steel plate refers to acid, alkali, salt and other chemical corrosive medium corrosion of steel plate.
不锈钢板钢板种很多,性能各异,它在发展过程中逐步形成了几大类。按钢板的性能特点和用途分类,分为耐硝酸不锈钢板、耐硫酸不锈钢板、耐点蚀不锈钢板、耐应力腐蚀不锈钢板、高强不锈钢板等。
Stainless steel plate, a variety of steel, different properties, it gradually formed a few categories in the development process. According to the performance characteristics and use of steel plate classification, can be divided into nitric acid stainless steel plate, stainless steel plate, corrosion pitting stainless steel plate, corrosion-resistant stainless steel plate, high-strength stainless steel plate, etc..
按钢板的功能特点分类,分为低温不锈钢板、无磁不锈钢板、易切削不锈钢板、超塑性不锈钢板等。目前常用的分类方法是按钢板的组织结构特点和钢板的化学成分特点以及两者相结合的方法分类。
According to the functional characteristics of the steel plate classification, divided into low temperature stainless steel plate, non-magnetic stainless steel plate, easy cutting stainless steel plate, superplastic stainless steel plate. At present, the commonly used classification methods are classified according to the characteristics of the steel plate structure, the chemical composition of the steel plate and the combination of the two methods.
不锈钢的耐腐蚀性主要取决于它的合金成分和内部的组织结构,起主要作用的是铬元素。铬具有很高的化学稳定性,能在钢表面形成钝化膜,使金属与外界隔离开来,保护钢板不被氧化,增加钢板的抗腐蚀能力。钝化膜破坏后,抗腐蚀性就下降。
The corrosion resistance of stainless steel depends mainly on its alloy composition and internal structure, and chromium is the main element. Chromium has high chemical stability, can form a passive film on the steel surface, so that the metal is isolated from the outside, protect the steel plate from oxidation and increase the corrosion resistance of the steel plate. When the passive film is destroyed, the corrosion resistance will decrease.
