</p> <p> <br /> </p> <p> <br /> </p> <p> 不銹鋼是靠其表面形成的一層極薄而堅(jiān)固細(xì)密的、穩(wěn)定的富鉻氧化膜（防護(hù)膜），防止氧原子的繼續(xù)滲入、氧化，而獲得抗銹蝕的能力。一旦有某種原因，這種薄膜遭到了不斷地破壞，空氣或液體中氧原子就會(huì)不斷地滲入或金屬中鐵原子不斷地析離出來(lái)，形成疏松的氧化鐵，金屬表面也就不斷的銹蝕。這種表面膜受到破壞的形式很多，常見的有以下幾種： </p> <p> 1）、不銹鋼表面存積著含有其它金屬元素的粉塵或異類金屬顆粒的附著物，在潮濕的空氣中，附著物與不銹鋼之間的冷凝水，將二者連成一個(gè)微電池，引發(fā)了電化學(xué)反應(yīng)，保護(hù)膜受到破壞，稱之為電化學(xué)腐蝕。 </p> <p> 2），常州347H不銹鋼廠家、不銹鋼表面粘附有機(jī)物汁液（瓜果、蔬菜、面湯等），在有水氧情況下，構(gòu)成有機(jī)酸，長(zhǎng)時(shí)間則有機(jī)酸對(duì)金屬表面的腐蝕。 </p> <p> 3）、不銹鋼表面粘附含有酸、堿、鹽類物質(zhì)（如裝飾墻壁的堿水、石灰水等），引起局部腐蝕。 </p> <p> 4）、在有污染的空氣中（如含有大量硫化物、氧化碳、氧化氮的大氣），遇冷凝水，形成硫酸，常州347H不銹鋼廠家、硝酸、醋酸液點(diǎn)，常州347H不銹鋼廠家，引起化學(xué)腐蝕。 </p> <p> <br /> </p> <p> <br /> 無(wú)錫市鑫中正特鋼有限公司提供不銹鋼，有想法可以來(lái)我司咨詢！常州347H不銹鋼廠家</p><div

當(dāng)不銹鋼表面出現(xiàn)褐色銹斑點(diǎn)的時(shí)候，人們大概驚奇——“不銹鋼是不生銹的”，“生銹就不是不銹鋼了”，“可能是鋼質(zhì)出現(xiàn)了問(wèn)題”……其實(shí)，這是對(duì)不銹鋼缺乏了解的錯(cuò)誤看法。不銹鋼在一定的條件下也會(huì)生銹的。不銹鋼具有抵抗大氣氧化的能力——即不銹性；同時(shí)，也具有在含酸、堿、鹽的介質(zhì)中耐腐蝕的能力——即耐蝕性；但是，其抗腐蝕能力的大小是隨其鋼質(zhì)本身的化學(xué)組成、加互狀態(tài)、使用條件及環(huán)境介質(zhì)類型而改變的。如：304鋼在干燥清潔的大氣中，有優(yōu)良的抗銹蝕能力，但是，將它移到海濱地區(qū)，在含有大量鹽份的海霧中，很快就會(huì)生銹了。因此，不是一種不銹鋼，在環(huán)境下都能耐腐蝕不生銹的。

隨著316不銹鋼管行業(yè)市場(chǎng)不斷飽和，316不銹鋼管企業(yè)都在積極尋找突破的方法，而隨著農(nóng)村城鎮(zhèn)化建設(shè)進(jìn)程不斷加快，這一市場(chǎng)商機(jī)無(wú)限擴(kuò)大。而如何抓住這一大好機(jī)遇，大力拓展農(nóng)村城鎮(zhèn)市場(chǎng)，是不少316不銹鋼管企業(yè)共同思考的問(wèn)題。

導(dǎo)致不銹鋼板生銹的主要因素有三點(diǎn)： </p> <p> 其一：合金元素的的含量，一般地說(shuō)鉻的含量在10.5%鋼就不易生銹了。鉻鎳的含量越高防腐性就越好，如304材質(zhì)鎳要的含量在8-10%，鉻的含量達(dá)到18-20%，這樣的不銹鋼板在一般情況下是不會(huì)生銹的。 </p> <p> 其二：生產(chǎn)企業(yè)的冶煉工藝也會(huì)影響不銹鋼板的耐腐蝕性。冶煉技術(shù)好、設(shè)備先進(jìn)、工藝先進(jìn)的大的不銹鋼板廠無(wú)論是在合金元素的控制，雜質(zhì)的去除、鋼坯冷卻溫度的控制都能得到保證，因此產(chǎn)品質(zhì)量穩(wěn)定可靠，內(nèi)在質(zhì)量好,不易生銹。反之一些小的鋼廠設(shè)備落后，工藝落后，冶煉過(guò)程中，雜質(zhì)不能去除，生產(chǎn)的產(chǎn)品難免會(huì)生銹。 </p> <p> 其三：外部環(huán)境，氣候干燥通風(fēng)好的環(huán)境不易生銹。而空氣濕度大，連續(xù)陰雨天氣、或空氣中含酸堿度大的環(huán)境地區(qū)就易生銹。304材質(zhì)不銹鋼板，如果周邊環(huán)境太差也是會(huì)生銹的。 </p> <p> <br /> </p> <p> <br /> 常州347H不銹鋼廠家</p></p><br
