不銹鋼板一般是不銹鋼板和耐酸鋼板的總稱。不銹鋼板是指耐大氣、蒸汽和水等弱介質腐蝕的鋼板，而耐酸鋼板則是指耐酸、堿、鹽等化學浸蝕性介質腐蝕的鋼板。
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.

不銹鋼板鋼板種很多，性能各異，它在發展過程中逐步形成了幾大類。按鋼板的性能特點和用途分類，分為耐硝酸不銹鋼板、耐硫酸不銹鋼板、耐點蝕不銹鋼板、耐應力腐蝕不銹鋼板、高強不銹鋼板等。
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..
按鋼板的功能特點分類，分為低溫不銹鋼板、無磁不銹鋼板、易切削不銹鋼板、超塑性不銹鋼板等。目前常用的分類方法是按鋼板的組織結構特點和鋼板的化學成分特點以及兩者相結合的方法分類。
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.
不銹鋼的耐腐蝕性主要取決于它的合金成分和內部的組織結構，起主要作用的是鉻元素。鉻具有很高的化學穩定性，能在鋼表面形成鈍化膜，使金屬與外界隔離開來，保護鋼板不被氧化，增加鋼板的抗腐蝕能力。鈍化膜破壞后，抗腐蝕性就下降。
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.
