大多出于成本方面考慮），部分客戶甚至要求-15%。①DDQ（deepdrawingquality）材：是指用于深拉（沖）用途的材料，也就是大家所說的的軟料，這種材料的主要特點(diǎn)是延伸率較高（≧53%），硬度較低（≦170%），內(nèi)部晶粒等級(jí)在，深沖性能較好。許多生產(chǎn)保溫瓶、鍋類的企業(yè)，其產(chǎn)品的加工比（BLANKINGSIZE/制品直徑）一般都比較高，它們的加工比分別達(dá)、、、。SUS304DDQ用材主要就是用于這些要求較高加工比的產(chǎn)品，當(dāng)然加工比超過。如果原料延伸方面達(dá)不到的話，在加工深拉制品時(shí)產(chǎn)品極易產(chǎn)生裂紋、拉穿的現(xiàn)象，影響成品合格率，當(dāng)然也就加大了廠家的成本；②一般材：主要用于除了DDQ用途外的材料，這種材料的特點(diǎn)是延伸率相對(duì)較低（≧45%），而硬度相對(duì)較高（≦180HB），內(nèi)部晶粒度等級(jí)在，與DDQ用材比較，它的深沖性能相對(duì)稍差，它主要用于不需伸拉就能得到的制品，象一類餐具的勺、匙、叉、電器用具、鋼管用途等。但它與DDQ材相比有一個(gè)優(yōu)點(diǎn)，就是BQ性相對(duì)較好，這主要是由于它的硬度稍高的緣故。不銹鋼薄板是一種價(jià)格不高的材料，但是客戶對(duì)它的表面質(zhì)量要求非常高。不銹薄板在生產(chǎn)過程中不可避免會(huì)出現(xiàn)各種缺陷，如劃傷、麻點(diǎn)、沙孔、暗線、折痕、污染等，從而其表面質(zhì)量。</p><p> 膨脹系數(shù)小、抗氧化性好、抗應(yīng)力腐蝕優(yōu)良等特點(diǎn)，多用于制造耐大氣、水蒸氣、水及氧化性酸腐蝕的零部件。這類鋼存在塑性差、焊后塑性和耐蝕性明顯降低等缺點(diǎn)，因而限制了它的應(yīng)用。爐外精煉技術(shù)（AOD或VOD）的應(yīng)用可使碳、氮等間隙元素降低，因此使這類鋼獲得應(yīng)用。影響因素編輯不論不銹鋼板還是耐熱鋼板，奧氏體型的鋼板的綜合性能好，既有足夠的強(qiáng)度，又有極好的塑性同時(shí)硬度也不高，這也是它們被采用的原因之一。奧氏體型不銹鋼同絕大多數(shù)的其它金屬材料相似，其抗拉強(qiáng)度、屈服強(qiáng)度和硬度，隨著溫度的降低而提高；塑性則隨著溫度降低而減小。其抗拉強(qiáng)度在溫度15~80°C范圍內(nèi)增長是較為均勻的。更重要的是：隨著溫度的降低，其沖擊韌度減少緩慢，并不存在脆性轉(zhuǎn)變溫度。所以不銹鋼在低溫時(shí)能保持足夠的塑性和韌性。不銹鋼的耐熱性能是指高溫下，既有抗氧化或耐氣體介質(zhì)腐蝕的性能即熱穩(wěn)定性。鉻的影響鉻是奧氏體不銹鋼中主要的合金元素，奧氏體不銹鋼的不銹性和耐蝕性的獲得主要是由于在會(huì)質(zhì)作用下，鉻促進(jìn)了鋼的鈍化并使鋼保持穩(wěn)定鈍態(tài)的結(jié)果?！?鉻對(duì)組織的影響：在奧氏體不銹鋼中，鉻是強(qiáng)烈形成并穩(wěn)定鐵體的元素，縮小奧氏體區(qū)，隨著鋼中含量增加。選購時(shí)應(yīng)選擇經(jīng)質(zhì)量技術(shù)監(jiān)督局評(píng)定的***產(chǎn)品，客戶中有長時(shí)間使用見證和良好口碑是**直接有效的選購方法。</p><div

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，形成疏松的氧化鐵，金屬表面也就受到不斷的銹蝕。國內(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，甚至超過普通的低碳鋼。所以對(duì)不銹鋼的使用環(huán)境有要求。福建不銹鋼無縫管公司</p><p
