答:不锈钢一般系不锈钢和耐酸钢的总称。不锈钢系指耐大气、蒸汽和水等弱介质腐蚀的钢,而耐酸钢则系指耐酸、碱、盐等化学浸蚀性介质腐蚀的钢。不锈钢与耐酸钢在合金化程度上有较大差异。不锈钢虽然具有不锈性,但并不一定耐酸;而耐酸钢一般均具有不锈性。不锈钢钢种很多,性能又各异,常见的分类方法有:a.按钢的组织结构分类,如马氏体不锈钢
A: Stainless steel generally stainless steel and acid-resistant steel in general. Stainless steel refers to the resistance to atmospheric air, steam and water and other weak medium corrosion of steel, and acid-resistant steel refers to acid, alkali, salt and other chemical etching corrosive steel. Stainless steel and acid-resistant alloy in the degree of alloying are quite different. Although stainless steel with stainless steel, but not necessarily acid; and acid-resistant steel generally have a stainless steel. A lot of stainless steel, performance and different, the common classification methods are: a. According to the classification of steel structure, such as martensitic stainless steel
