“不銹鋼”一詞不僅僅是單純指一種不銹鋼，而是表示一百多種工業(yè)不銹鋼，所開發(fā)的每種不銹鋼都在其特定的應(yīng)用領(lǐng)域具有良好的性能。

成功的關(guān)鍵首先是要弄清用途，然后再確定正確的鋼種。和建筑構(gòu)造應(yīng)用領(lǐng)域有關(guān)的鋼種通常只有六種。

不銹鋼是靠其表面形成的一層極薄而又堅固細(xì)密的穩(wěn)定的富鉻氧化膜（防護膜），防止氧原子繼續(xù)滲入、繼續(xù)氧化，而獲得抗腐蝕的能力。

一但有某種原因，這種薄膜遭到不斷的破壞，空氣或液體中和氧原子就會不斷滲入或金屬中鐵原子不斷地析離出來，形成疏松的氧化鐵，

金屬表面也就受到不斷的銹蝕。

The term "stainless steel" does not simply refer to a kind of stainless steel, but means more than 100 industrial stainless steel,

each stainless steel developed has good performance in its specific application field. The key to success is first to identify the purpose,

and then to determine the right kind of steel. There are usually only six kinds of steel related to the application field of architectural construction.

Stainless steel is a very thin and strong and stable chromium rich oxide film (protective film), to prevent oxygen atoms to continue to penetrate,

and oxidation, and obtain corrosion resistance. For some reason, when the film is constantly damaged,

the air or liquid neutralization of oxygen atoms will constantly penetrate or the metal iron atoms are constantly separated, forming loose iron oxide,

and the metal surface is constantly corroded.
