不銹鋼知識匯總，需要請收藏
不銹鋼定義
不銹鋼是一種能夠抵抗腐蝕的高合金鋼.具有美觀的表面,不必經(jīng)過鍍色或油漆等表面處理,所以很多機(jī)械廠為表明自己的是不銹鋼，往往是不作任何油漆處理的，而黑材(所謂黑材就是一般鋼鐵的稱呼)是必須進(jìn)行防銹處理的。
不銹鋼的形態(tài)分類
不銹鋼可分為卷板、板材、型材、鋼管和零部件五大類，*重要的是卷和板。型材就是由板做成的各種不同型狀的材料，有角鋼、扁鋼、工字鋼、槽鋼。鋼管主要是指無縫鋼管，和無縫鋼管相對的就是焊管，區(qū)別在于是否一次成型。零部件主要是指彎頭和法蘭和其他小東西.
卷材和板材實(shí)際上一樣的，出廠形式不一樣而已，卷材就是一卷一卷的，板材是一張一張的，如果出廠就是板材，也叫原裝板，一般是厚板，因?yàn)楹芎竦脑挘菬o法成卷的，一般16毫米以上就不能成卷了.
有卷的，有板的，很多時(shí)候是板，卷和板的價(jià)格也是不一樣的，如果是采購卷，就是按實(shí)際稱重計(jì)算的，所以價(jià)格高，板是按照理論計(jì)算的，價(jià)格就低，原因是有下差，如10mm厚的實(shí)際可能是9.6mm，這中間就會有價(jià)差。
不銹鋼的簡易分類
不銹鋼可以粗淺的分為200系列，300系列和400系列三大類，其中300系列是*常用的，200系列和400系列一定程上是300系列的替代品，而嚴(yán)格來講400系列不叫不銹鋼，叫不銹鐵，因?yàn)槔锩娌缓囋?，所以用磁鐵可以吸引住。而200系列和300系列是有鎳的，所以是沒有磁性的，吸鐵吸不住。
304是300系列中*常見的品種，所以一般從304的價(jià)格變化可以判斷出整個(gè)不銹鋼的價(jià)格走勢。200系列含鎳少，400系列不含鎳，300系列含鎳*多，所以受鎳價(jià)影響*大的是300系列。
300系列可以簡分為304、304L、316、316L、321、309S、310S等等，區(qū)分的依據(jù)是各種金屬元素的含量不同，含量不同的不銹鋼的特性也不相同，304和304L的區(qū)別在于碳（C）含量的不同，帶L的是表示含碳低，也叫低碳，316和316L的區(qū)別也是一樣。
不銹鋼板根據(jù)軋機(jī)(軋機(jī)是軋制板的機(jī)器名)軋制工藝的不同，分成熱軋和冷軋，熱軋通常標(biāo)為****冷軋標(biāo)為2B或者BA(BA比2B的表面好、要亮，接近鏡子，*好的就是鏡面，鏡面沒有現(xiàn)貨，都需要加工)，比如304很多時(shí)候是采購板，那就意味著卷必須通過機(jī)器開平成板的形式，這種機(jī)器就是開平機(jī)。通過開平機(jī)開平可以開成不同的長度，如果不是常規(guī)長度就叫定開，意思就是定開尺寸，因?yàn)榭蛻舾鶕?jù)實(shí)際需要，常常會提出不同的長度要求，這個(gè)時(shí)候卷就顯得重要了，常規(guī)的板就不能滿足要求了。
國產(chǎn)冷軋一般在3毫米以下，熱軋一般在3毫米以上，3毫米厚度的既有熱軋，也有冷軋，但是進(jìn)口的冷軋板厚度可以達(dá)到4毫米以下甚至6毫米以下。熱軋3毫米到12毫米的板叫中板，12毫米以上的叫厚板，可以厚到120毫米以上，并稱熱軋中厚板，而冷軋就是冷軋薄板了。
不銹鋼板理論重量的簡易計(jì)算方法
板重=比重×厚度(mm)×寬度(m)×長度(m)(mm是毫米的單位，m是米的單位)
在工程機(jī)械領(lǐng)域由于講究精度尺寸，世界上都采用毫米為單位1000毫米=1米，1毫米=100絲。
按這個(gè)公式得出的重量是公斤(KG)，要**到小數(shù)點(diǎn)后兩位，因?yàn)椴讳P鋼價(jià)格貴，交易量大，小數(shù)點(diǎn)后的數(shù)字也就很重要了，因此錢款也要**到小數(shù)點(diǎn)后兩位。
不銹鋼的比重(KG)
不同的不銹鋼有不同的比重：
A，400系列比重是7.75
B，304.321.304N.201.202.304L..301.比重是7.93
C，310S.309S.316.316L比重是7.98。
用鋼號對照表
世界各國對不銹鋼的稱呼各有不同，市場常接觸的是中國和美國的，叫國標(biāo)和美標(biāo)，上面說到的200系列300系列400系列就是美標(biāo)，美標(biāo)由于通俗易懂，所以通常叫的都是美標(biāo)。

主要不銹鋼種類的特性和用途
304：作為一種用途廣泛的鋼材，具有良好的耐蝕性，耐熱性，低溫強(qiáng)度和機(jī)械性，沖壓，彎曲等熱加工性好，無熱處理硬化現(xiàn)象，無磁性，使用溫度零下193度到正800度。
用途:餐具，廚具，熱水器，鍋爐，汽車配件，醫(yī)療器械，食品機(jī)械，儲存酒具，壓力容器（化工機(jī)械，化工裝備）。
304L作為低碳的304鋼，在一般狀態(tài)下，耐蝕性和304差不多，但在焊接后和消除應(yīng)力后，它抗間晶腐蝕性好，在未進(jìn)行熱處理的情況下，也能保持良好的耐蝕性，一般在400度下使用，
用途：石化產(chǎn)業(yè)，建材。
321在304鋼中添加Ti元素，來防止間晶腐蝕，適用于正430到900度以下，無磁性；
用途：汽車排氣，熱交換器，集裝箱等焊接后不進(jìn)行熱處理的產(chǎn)品，由于加入Ti元素，就不合適制作食品加工設(shè)備。
316低碳，添加MO元素，所以他的耐蝕性和耐大氣腐蝕性和高溫強(qiáng)度性能特別好，可以在苛刻條件下使用，適合在900度以下使用，無磁性。
用途：海水里使用的設(shè)備，化工，染料，造紙，醋酸，肥料等生產(chǎn)設(shè)備，食品工業(yè)和沿海地區(qū)設(shè)施，對抗間晶腐蝕有特別要求的產(chǎn)品。
309S/310S這兩種材質(zhì)，鎳和鉻的含量比較高，同時(shí)增加Si 的含量，使其具有耐高溫和耐蝕性，其中309S可以承受980以下反復(fù)加熱，310S使用溫度達(dá)到1200度，連續(xù)使用溫度可在1150度，無磁性。
用途：適用高溫電爐設(shè)備，干燥設(shè)備等關(guān)鍵部位，爐用材料，航空，石化，電力等。
200系列類似于304價(jià)格便宜經(jīng)濟(jì)性。
用途：食品加工器皿，廚房設(shè)備，食品加工設(shè)備，過濾器，牛奶罐，耐用消費(fèi)品，洗衣機(jī)配件，熱水器，鋼制家具，建筑裝潢，裝飾。耐疲勞方面，201硬度較大，韌性不如304,還是304的耐疲勞度好些。
國標(biāo)稱呼中的元素含量一般是指含量的中間值，為理論值，可大可小。
什么叫公差
這是一個(gè)很重要的名詞，公差就是公認(rèn)允許的長度或厚度偏差.因?yàn)樵诎宀牡纳a(chǎn)過程里，出于各種原因很難。出來的實(shí)際厚度往往是達(dá)不到理論的厚度，比如6毫米的板，只有5.6毫米，這就是公差，在國內(nèi)公差往往就是負(fù)公差，當(dāng)然也有正公差，但是很少。在買賣板時(shí)，通常是按理論厚度來計(jì)算，這也是為什么理論價(jià)比稱重價(jià)低的原因，公差還有大小之分，價(jià)格也不一樣，大公差的價(jià)格便宜.舉例說明，6毫米的，如果是5.5以下就是大公差了。
