一、不銹鋼是什么鋼？不銹鋼是鋼的一個(gè)種類(lèi)，鋼是指含有碳（C）量在2%以下的稱(chēng)之為鋼，大于2%是鐵。鋼在冶煉過(guò)程中加入鉻（Cr）、鎳（Ni）、錳（Mn）、硅（Si）、鈦（Ti）、鉬（Mo）等合金元素改善了鋼的性能使鋼具有了耐腐性（即不上銹）就是我們常說(shuō)的不銹鋼。二、為什么不銹鋼有不同的鋼號(hào)？不銹鋼在冶煉過(guò)程當(dāng)中，由于加入合金元素品種不同，不同品種加入量的不同。其特性也是不同的，為了加以區(qū)別則冠上了不同的鋼號(hào)，下面是常見(jiàn)裝飾用不銹鋼不同鋼號(hào)“合金元素”含量表*供參考：三、什么樣的不銹鋼不易生銹？影響不銹鋼銹蝕的主要因素有三點(diǎn)：其一：合金元素的的含量，一般地說(shuō)鉻的含量在。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%，這樣的不銹鋼在一般情況下是不會(huì)生銹的。其二：生產(chǎn)企業(yè)的冶煉工藝也會(huì)影響不銹鋼的耐腐蝕性。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，數(shù)控微信公號(hào)cncdar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。其三：外部環(huán)境。309s不銹鋼H型鋼廠家不銹鋼H型鋼定制生產(chǎn)制作——江蘇進(jìn)百洪。</p><div

可能是鋼質(zhì)出了問(wèn)題”。其實(shí)，這是對(duì)不銹鋼缺乏了解的一種片面的錯(cuò)誤看法。不銹鋼在一定條件下也會(huì)生銹的。不銹鋼具有抵抗大氣氧化的能力一即不銹性，同時(shí)也具有在含酸、堿、鹽的介質(zhì)中耐腐蝕的能力即耐腐蝕性。但其抗腐蝕能力的大小是隨其鋼質(zhì)本身化學(xué)組成，相互狀態(tài)，使用條件及環(huán)境介質(zhì)類(lèi)型而改變的。如304材料，在干燥清潔的大氣中，有優(yōu)良的抗腐蝕能力，但將它移到海濱地區(qū)，在含有大量鹽分的海霧中，很快就會(huì)生銹的。因此，不是任何一種不銹鋼，在任何時(shí)候都能耐腐蝕，不生銹的。不銹鋼是靠其表面形成的一層極薄而又堅(jiān)固細(xì)密的穩(wěn)定的富鉻氧化膜（防護(hù)膜），防止氧原子繼續(xù)滲入、繼續(xù)氧化，數(shù)控微信公號(hào)cncdar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(huì)不斷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，金屬表面也就受到不斷的銹蝕。這種表面膜受到破壞的形式很多，日常生活中多見(jiàn)的有如下幾種：1、不銹鋼表面存積蓄含有其它金屬元素的粉塵或異類(lèi)金屬顆料的附著物，在潮濕的空氣中，附著物與不銹鋼間的冷凝水，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(chēng)之謂電化學(xué)腐蝕。</p><p>
