鈑金廠用的304與20l拉絲不銹鋼板的簡(jiǎn)單方法拉絲不銹鋼板因其良好的耐腐蝕性往往被用著內(nèi)層（即直接與水接觸），20l不銹鋼因?yàn)槟透g性較差，不能用著內(nèi)層，往往被用在保溫水箱的外層。但是20l比304價(jià)格低廉，往往會(huì)被一些不良商家冒充304使用，用20l不銹鋼制作的不銹鋼水箱使用壽命極短，往往l-2年就能被水腐蝕，給使用者留下安全壞處。下面教大家用簡(jiǎn)單的方法識(shí)別這兩種材質(zhì)：l.不銹鋼水箱用到的304與20l不銹鋼，表面通常為亞光。所以我們通過肉眼看、手觸摸的方式鑒別。肉眼看304不銹鋼具有很好的光澤發(fā)亮，手觸摸很順滑；20l不銹鋼則顏色發(fā)暗沒有光澤，觸摸有比較粗糙不光滑的感覺。另外將手沾濕水，分別觸摸2種不銹鋼板，觸摸后304板上的水漬手印比較容易擦除，20l不容易擦除。2.用磨光機(jī)裝上砂輪片輕輕打磨兩種板，打磨時(shí)20l板的火花比較長(zhǎng)、粗、多，反之304板的火花比較短、細(xì)、少。打磨時(shí)力量務(wù)必輕，且2種打磨力道一致，方便區(qū)別。3.用不銹鋼酸洗膏分別涂抹在2種不銹鋼板上。2分鐘后，看涂抹處不銹鋼顏色的變化。顏色發(fā)黑為20l，發(fā)白或不變色為304。

拉絲不銹鋼板表面光潔，有較高的可塑性、韌性和機(jī)械強(qiáng)度，耐酸、堿性氣體、溶液和其他介質(zhì)的腐蝕。它是一種不容易生銹的合金鋼，但不是肯定不生銹。不銹鋼板是指耐大氣、蒸汽和水等弱介質(zhì)腐蝕的鋼板，而耐酸鋼板則是指耐酸、堿、鹽等化學(xué)浸蝕性介質(zhì)腐蝕的鋼板。那么20l不銹鋼板與304不銹鋼板怎么區(qū)分呢？下面就帶大家一起來看看吧。一.不銹鋼20l304區(qū)別l、規(guī)格：常用的拉絲不銹鋼板材分為20l和304兩種型號(hào)，實(shí)際是是成分不同，304質(zhì)量好一些，但價(jià)格貴，20l差一些。304為進(jìn)口不銹鋼板,20l為國(guó)產(chǎn)不銹鋼板。2、20l是節(jié)Ni鋼種，30l鋼的替代鋼。經(jīng)冷加工后具有磁性，用于鐵路車輛。3、304是得到**廣泛應(yīng)用的不銹鋼、耐熱鋼。用于食品生產(chǎn)設(shè)備、普通化工設(shè)備、核能等。4、20l是含錳較高，表面很亮帶有暗黑的亮，含錳較高容易生銹。304含鉻較多，表面呈現(xiàn)啞光，不生銹，兩種放在一起就有比較了。**重要的就是耐腐蝕性能不同，20l的耐腐蝕性能很差，所以價(jià)格就要便宜很多。又因?yàn)?0l含鎳低，所以價(jià)格比304的低，于是耐腐蝕性能就不如304的了。5、20l與304之間的區(qū)別就是含鎳的問題。而且304的價(jià)格現(xiàn)在都比較貴，一般都要接近50000一噸。

裂紋和氣孔。裂紋的出現(xiàn)頻率很高，一般裂紋分為熱裂紋和冷裂紋兩種。由于液體金屬在凝固過程中或略低于固相線溫度下，產(chǎn)生沿晶間邊界的、斷口上就會(huì)形成具有氧化色的熱裂紋。在固態(tài)時(shí)發(fā)生相變，或有擴(kuò)散氫存在，以及冷卻時(shí)在過大的焊接收縮應(yīng)力作用下，就會(huì)生成的具有穿晶性質(zhì)的、斷口發(fā)亮、沒有氧化色的冷裂紋。如果在使用焊絲時(shí)不合乎標(biāo)準(zhǔn)，焊接時(shí)高溫停留時(shí)間過長(zhǎng)，造成氧化、過熱和晶粒度過度長(zhǎng)大，材料本身雜質(zhì)較多，或材料本身易淬硬時(shí)均易產(chǎn)生裂紋。而在焊件、焊絲表面有油污、氧化皮、鐵銹等情況，或在潮濕環(huán)境中進(jìn)行焊接，或者氬氣純度低，或氬氣保護(hù)氣不佳以及熔池高溫氧化、飛濺等情況下都容易產(chǎn)生氣孔。不銹鋼焊管的焊接要求操作人員要詳細(xì)了解不同種類的不銹鋼的特性，此外，也要熟練掌握不銹鋼焊接技術(shù)的具體方法，因此，生產(chǎn)廠家也要進(jìn)一步加強(qiáng)操作人員的技術(shù)培訓(xùn)。
