對(duì)不銹鋼表面的鈍化膜都發(fā)生破壞作用。因此，對(duì)不銹鋼表面必須進(jìn)行定期的清潔保養(yǎng)，以保持其華麗的表面及延長(zhǎng)使用壽命。清洗不銹鋼表面時(shí)必須注意不發(fā)生表面劃傷現(xiàn)象。避免使用漂白成分以及研磨劑的洗滌液，鋼絲球、研磨工具等，為除掉洗滌液，洗滌完成后再用潔凈水沖洗表面。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,而獲得抗銹蝕能力。一旦有某種原因，這種薄膜受到不斷的破壞，空氣或液體中的氧原子就會(huì)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。國(guó)內(nèi)很多廠家出于成本考慮，在不銹鋼中降低了鉻、鎳，增加了錳的含量。**認(rèn)為，不銹鋼之所以能不銹，就是因?yàn)橛秀t和鎳的存在，降低這兩種成分的含量會(huì)降低防銹性能。不銹鋼機(jī)械加工過(guò)程中的注意事項(xiàng)：加工區(qū)：不銹鋼件的加工區(qū)域應(yīng)相對(duì)固定。加工區(qū)的平臺(tái)應(yīng)采取防護(hù)措施，如鋪橡膠墊等。不銹鋼件加工時(shí)應(yīng)避免對(duì)不銹鋼件表面防護(hù)層的損傷。不銹鋼產(chǎn)品不銹鋼產(chǎn)品使用環(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(guò)普通的低碳鋼。所以對(duì)不銹鋼的使用環(huán)境有要求。</p><p> 象劃傷、折痕等這些缺陷是高級(jí)材不允許出現(xiàn)的，而麻點(diǎn)、沙孔這種缺陷在勺、匙、叉、制作時(shí)也是決不允許的，因?yàn)閽伖鈺r(shí)很難拋掉它。需要根據(jù)表面各種缺陷出現(xiàn)的程度和頻率，來(lái)確定其表質(zhì)量等級(jí)，從而來(lái)確定產(chǎn)品等級(jí)。物理性能編輯與碳鋼比較1、密度碳鋼的密度略高于鐵素體和馬氏體型不銹鋼，而略低于奧氏體型不銹鋼；2、電阻率電阻率按碳鋼、鐵素體型、馬氏體型和奧氏體型不銹鋼排序遞增；3、線膨脹系數(shù)大小的排序也類似，奧氏體型不銹鋼高而碳鋼小；4、碳鋼、鐵素體型和馬氏體型不銹鋼有磁性，奧氏體型不銹鋼無(wú)磁性，但其冷加工硬化生成馬氏體相變時(shí)將會(huì)產(chǎn)生磁性，可用熱處理方法來(lái)消除這種馬氏體組織而恢復(fù)其無(wú)磁性。奧氏體型不銹鋼與碳鋼相比，具有下列特點(diǎn)：1）高的電阻率，約為碳鋼的5倍。2）大的線膨脹系數(shù)，比碳鋼大40%，并隨著溫度的升高，線膨脹系數(shù)的數(shù)值也相應(yīng)地提高。3）低的熱導(dǎo)率，約為碳鋼的1/3。典型用途編輯大多數(shù)的使用要求是長(zhǎng)期保持建筑物的原有外貌。在確定要不銹鋼產(chǎn)品不銹鋼產(chǎn)品選用的不銹鋼類型時(shí)，主要考慮的是所要求的審美標(biāo)準(zhǔn)、所在地大氣的腐蝕性以及要采用的清理制度。然而，其它應(yīng)用越來(lái)越多的只是尋求結(jié)構(gòu)的完整性或不透水性。例如。焊縫不合格是因焊接工藝參數(shù)選擇不當(dāng)，或操作技術(shù)不熟練，導(dǎo)致焊縫高低寬窄不一，焊縫成形不良。</p><div
