展開全部304不銹鋼材質(zhì)硬度：≤187HB；≤90HRB；≤200HV。304不銹鋼是不銹鋼中常見的一種材質(zhì)，密度為g/cm3，業(yè)內(nèi)也叫做18/8不銹鋼。耐高溫800度，具有加工性能好，韌性高的特點(diǎn)，***使用于工業(yè)和家具裝飾行業(yè)和食品醫(yī)療行業(yè)。市場上常見的標(biāo)示方法中有00Cr19Ni10，SUS304，其中00Cr19Ni10一般表示國標(biāo)標(biāo)準(zhǔn)生產(chǎn)，一般表示ASTM標(biāo)準(zhǔn)生產(chǎn)，SUS304表示日標(biāo)標(biāo)準(zhǔn)生產(chǎn)。304是一種通用性的不銹鋼，它***地用于制作要求良好綜合性能（耐腐蝕和成型性）的設(shè)備和機(jī)件。為了保持不銹鋼所固有的耐腐蝕性，鋼必須含有18%以上的鉻,8%以上的鎳含量。304不銹鋼是按照美國ASTM標(biāo)準(zhǔn)生產(chǎn)出來的不銹鋼的一個(gè)牌號。拓展資料：組成元素：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。代表性能的有13鉻鋼，18-8鉻鎳鋼等高合金鋼。不銹鋼防銹的機(jī)理是合金元素形成致密氧化膜，隔絕氧接觸，阻止繼續(xù)氧化。所以不銹鋼并不是“不銹”。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。</p><p> 1、45——質(zhì)量碳素結(jié)構(gòu)鋼，是**常用中碳調(diào)質(zhì)鋼。首要特征:**常用中碳調(diào)質(zhì)鋼，歸納力學(xué)功能杰出，淬透性低，水淬時(shí)易生裂紋。小型件宜選用調(diào)質(zhì)處理，大型件宜選用正火處理。運(yùn)用舉例:首要用于制作強(qiáng)度高的運(yùn)動(dòng)件，如透平機(jī)葉輪、壓縮機(jī)活塞。軸、齒輪、齒條、蝸桿等。焊接件留意焊前預(yù)熱，焊后消除應(yīng)力退火。2、Q235A（A3鋼）——**常用的碳素結(jié)構(gòu)鋼。首要特征:具有高的塑性、耐性和焊接功能、冷沖壓功能，以及必定的強(qiáng)度、好的冷彎功能。運(yùn)用舉例:***用于一般要求的零件和焊接結(jié)構(gòu)。如受力不大的拉桿、連桿、銷、軸、螺釘、螺母、套圈、支架、機(jī)座、建筑結(jié)構(gòu)、橋梁等。3、40Cr——運(yùn)用*****的鋼種之一，屬合金結(jié)構(gòu)鋼。首要特征:經(jīng)調(diào)質(zhì)處理后，具有杰出的歸納力學(xué)功能、低溫沖擊韌度及低的缺口敏感性，淬透性杰出，油冷時(shí)可得到較高的疲勞強(qiáng)度，水冷時(shí)雜亂形狀的零件易發(fā)生裂紋，冷彎塑性中等，回火或調(diào)質(zhì)后切削加工性好，但焊接性欠好，易發(fā)生裂紋，焊前應(yīng)預(yù)熱到100～150℃，一般在調(diào)質(zhì)狀況下運(yùn)用，還能夠進(jìn)行碳氮共滲和高頻外表淬火處理。運(yùn)用舉例:調(diào)質(zhì)處理后用于制作中速、中載的零件，如機(jī)床齒輪、軸、蝸桿、花鍵軸、頂針套等。可以作為控制工藝傲綜合試驗(yàn)、抽樣分析和標(biāo)定數(shù)據(jù)，也可以在生產(chǎn)線上進(jìn)行硬度檢驗(yàn)。</p><div

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。從金相學(xué)角度分析，因?yàn)椴讳P鋼含有鉻而使表面形成很薄的鉻膜，這個(gè)膜隔離開與鋼內(nèi)侵入的氧氣起耐腐蝕的作用。為了保持不銹鋼所固有的耐腐蝕性，鋼必須含有12%以上的鉻。304是一種通用性的不銹鋼，它***地用于制作要求良好綜合性能（耐腐蝕和成型性）的設(shè)備和機(jī)件。304不銹鋼是按照美國ASTM標(biāo)準(zhǔn)生產(chǎn)出來的不銹鋼的一個(gè)牌號。304相當(dāng)于我國的0Cr19Ni9(0Cr18Ni9)不銹鋼。304含鉻19%，含鎳9%。硬度計(jì)是一種硬度測試儀器。維式硬度機(jī)供應(yīng)商</p><p
