大半數人覺（jiào）得不鏽鋼是絕（jué）對化進行不肯（kěn）進行金星的，而進行金星的就並（bìng）非不鏽鋼（gāng）了（le）。夠意思，一部分含鎳低的不鏽鋼鐵質在準譜兒的具體（tǐ）條件下也會進行金（jīn）星的。不鏽鋼方管具備對手空氣液化的實際能力，與此同時也具（jù）備在含酸、堿、鹽的電介質中耐破壞的實際能力。但其抗破壞實際能力的大大小小是隨其鋼質自己化學構成、加互情況、采用具體條件及環境電介質種類而成為的。因為這個原因，並非任意一種相關情況其中一（yī）種不鏽（xiù）鋼，在任意一種相關情況環境（jìng）渾渾沌（dùn）沌（dùn）本領破壞不進行金（jīn）星（xīng）。
Most people think that stainless steel will never rust, but stainless steel will not rust. In fact, some stainless steel materials with low nickel content will rust under certain conditions. Stainless steel square tube has the ability to resist atmospheric oxidation, but also has the ability to resist corrosion in medium containing acid, alkali and salt. However, the corrosion resistance of the steel varies with its chemical composition, additive state, service conditions and the type of environmental medium. Therefore, not any stainless steel, in any environment can resist corrosion and rust.
Square tube
不鏽（xiù）鋼是靠其要樣兒逐漸形成的關於一層極薄而著名密切的保持穩定的富鉻液化膜來避免氧亞原子參加液化，而取得抗（kàng）剝蝕的實際能力。該地膜在滿足相關條件（jiàn）時受到風吹雨打，不鏽鋼（gāng）方管就會作為抗鏽實（shí）際能力。通（tōng）常中多見的風吹雨打方法猶如下關於（yú）四種：
Stainless steel is formed by a very thin, solid, compact and stable chromium-rich oxide film on its surface to prevent oxygen atoms from penetrating into oxidation, and to obtain the ability to resist corrosion. If the film is destroyed, the stainless steel square pipe will lose its rust resistance. There are four common ways of destruction in daily life:
（一）不鏽鋼（gāng）方（fāng）管要樣兒進行黏著考（kǎo）古物（wù）汁液，在有水氧狀（zhuàng）況（kuàng）下，組成考古酸，長時段則考古酸對非金屬要樣兒的破壞。
(1) The surface of stainless steel square tubes is adhered with organic juice, which forms organic acids in the presence of water and oxygen, and corrodes the metal surface for a long time.
（二）在（zài）有造成汙染的大（dà）氣中（zhōng），遇冷凝水，逐漸形成亞硫酸、王水、醋酸液點，進行造成化（huà）學破壞。
(2) In polluted air, when it encounters condensate water, it forms sulfuric acid, nitric acid and acetic acid liquid points, which cause chemical corrosion.
（三）不鏽（xiù）鋼方（fāng）管（guǎn）要樣兒存積著包括其餘非金屬因（yīn）素的（de）煙塵或異（yì）類非金屬細（xì）顆（kē）粒物的（de）需要物，在濕氣的大氣中，需要物（wù）與（yǔ）不鏽鋼間的冷凝水，將雙（shuāng）方連成其中一個微幹電池，抓住（zhù）了電化學影響，維護膜進行接受風吹雨打，稱（chēng）之謂電化學破壞。
(3) The surface of stainless steel square tubes contains dust containing other metal elements or adhesives of different metal particles. In humid air, the adhesives and the condensate water between the adhesives and stainless steel connect the two into a micro-battery, which causes electrochemical reaction and damages the protective film. It is called electrochemical corrosion.
（四）不鏽鋼方（fāng）管要樣兒進行黏著包括酸、堿、鹽類資料，進行造成部分破壞（huài）。
(4) The adherence of stainless steel square tubes to the surface contains acids, alkalis and salts, which causes local corrosion.
