不銹鋼是鋼的一個(gè)種類，鋼是指含有碳（C）量在2%以下的稱之為鋼，大于2%是鐵。鋼在冶煉過程中加入鉻（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）就是我們常說的不銹鋼。 </p> <p> <br /> </p> <p> 為什么不銹鋼有不同的鋼號？ </p> <p> 不銹鋼在冶煉過程當(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，下面是常見不銹鋼不同鋼號“合金元素”含量表*供參考： </p> <p> 鋼號碳硅錳磷硫鉻鎳鉬銅 </p> <p> 304 ≤0.08 ≤1.00 ≤2.00 ≤0.045 ≤0.03 18-20 8-10 </p> <p> 301 ≤0.15 ≤1.00

是碳含量較低的304不銹鋼的變種，用于需要焊接的場合。較低的碳含量使得在靠近焊縫的熱影響區(qū)中所析出的碳化物減******少，而碳化物的析出可能導(dǎo)致不銹鋼在某些環(huán)境中產(chǎn)生晶間腐蝕（焊接侵蝕）。 </p> <p> <br /> </p> <p> 304N 是一種含氮的不銹鋼，加氮是為了提高鋼的強(qiáng)度。 </p> <p> <br /> </p> <p> 305和384 不銹鋼含有較高的鎳，其加工硬化率低，適用于對冷成型性要求高的各種場合。 </p> <p> <br /> </p> <p> 308 不銹鋼用于制作焊條。 </p> <p> <br /> </p> <p> 309、310、314及330 不銹鋼的鎳、鉻含量都比較高，為的是提高鋼在高溫下的抗氧化性能和蠕變強(qiáng)度。而30S5和310S乃是309和310不銹鋼的變種，所不同者只是碳含量較低，為的是使焊縫附近所析出的碳化物減******少。330不銹鋼有著特別高的抗?jié)B碳能力和抗熱震性． </p> <p> <br /> </p> <p> 316和317 型不銹鋼含有鋁，因而在海洋和化學(xué)工業(yè)環(huán)境中的抗點(diǎn)腐蝕能力地優(yōu)于304不銹鋼。其中，316型不銹鋼由變種包括低碳不銹鋼316L、含氮的**度不銹鋼316N以及合硫量較高的易切削不銹鋼316F。 </p> <p> <br /> </p> <p> 321、347及348 是分別以鈦，鈮加鉭、鈮穩(wěn)定化的不銹鋼，適宜作高溫下使用的焊接構(gòu)件。348是一種適用于核動力工業(yè)的不銹鋼，對鉭和鉆的合量有著一定的。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><p> 鋼鐵材料相關(guān)術(shù)語 </p> <p>

不銹鋼是指合金元素總量高于2.5%，能夠抵抗空氣、蒸汽和水等腐蝕介質(zhì)的鋼鐵，是現(xiàn)代工業(yè)中一種較為重要的應(yīng)用材料，研究歷史已接近百年。不銹鋼因?yàn)榫哂泻芏鄡?yōu)良的性能，在很多的方面都有應(yīng)用。 </p> <p> <br /> </p> <p> 不銹鋼應(yīng)用，種類也很多，例如奧氏體不銹鋼和雙相不銹鋼等。不銹鋼不易生銹，因其表面的鈍化膜能減緩腐蝕介質(zhì)對基體的繼續(xù)腐蝕，起到保護(hù)基體的作用。應(yīng)用的環(huán)境不同，不銹鋼也會發(fā)生不同程度的腐蝕。如果能夠理解鈍化膜的形成機(jī)理，就可以預(yù)防很多腐蝕發(fā)生。 </p> <p> <br /> </p> <p> <br />

便用溫茺-196℃～800℃）。用途：家庭用品（1、2類餐具、櫥柜、室內(nèi)管線、熱水器、鍋爐、浴缸），汽車配件（風(fēng)擋雨刷、消聲器、模制品），醫(yī)療器具，建材，化學(xué)，食品工業(yè)，農(nóng)業(yè)，船舶部件。304圓棒304材料出現(xiàn)生銹現(xiàn)象，可能有以下幾個(gè)原因：1.使用環(huán)境中存在氯離子。氯離子存在，比如食鹽、汗跡、海水、海風(fēng)、土壤等等。不銹鋼在氯離子存在下的環(huán)境中，腐蝕很快，甚至超過普通的低碳鋼。所以對不銹鋼的使用環(huán)境有要求，而且需要經(jīng)常擦拭，除去灰塵，保持清潔干燥。（這樣就可以給他定個(gè)“使用不當(dāng)”。）美國有一個(gè)例子：某企業(yè)用一橡木容器盛裝某含氯離子的溶液，該容器已使用近百余年，上個(gè)世紀(jì)九十年代計(jì)劃更換，因橡木材料不夠現(xiàn)代，采用不銹鋼更換后16天容器因腐蝕泄漏。2.沒有經(jīng)過固溶處理。合金元素沒有溶入基體，致使基體組織合金含量低，抗蝕性能差。3.這種不含鈦和鈮的材料有天生的晶間腐蝕的傾向。加入鈦和鈮，再配以穩(wěn)定處理，可以減少晶間腐蝕。在空氣中或化學(xué)腐蝕介質(zhì)中能夠抵抗腐蝕的一種高合金鋼。不銹鋼是具有美觀的表面和耐腐蝕性能好，不必經(jīng)過鍍色等表面處理，而發(fā)揮不銹鋼所固有的表面性能,使用于多方面的鋼鐵的一種，通常稱為不銹鋼。上海?904L不銹鋼圓棒加工</p><p
