扁鋼，是指寬12-300mm、厚3-60mm、截面為長(zhǎng)方形并稍帶鈍邊的鋼材。扁鋼可以是成品鋼材，也可以做焊管的坯料和疊軋薄板用的薄板坯。主要用途：扁鋼作為成材可用于制箍鐵、工具及機(jī)械零件，建筑上用作房架結(jié)構(gòu)件、扶梯。 </p> <p> 扁鋼優(yōu)點(diǎn)：采用負(fù)偏差軋制，但按實(shí)際重量交貨，利用率較鋼板提高1～5個(gè)百分點(diǎn)。 </p> <p> 扁鋼可以按用戶需求，定厚、定寬、定長(zhǎng)生產(chǎn)，為用戶減少了切割，并節(jié)省工序，降低了人工、材料的消耗，同時(shí)也減少了原材料的加工損耗，省時(shí)、省力、省料。產(chǎn)品已專業(yè)用于鋼結(jié)構(gòu)制造業(yè)、機(jī)械制造業(yè)、汽車工業(yè)、礦山機(jī)械、起重機(jī)械及其它產(chǎn)業(yè)用材。基建圓鋼圓鋼質(zhì)量過(guò)硬，歡迎咨詢江陰市港都物資有限公司了解！</p><div

合金鋼分為低合金鋼、中合金鋼和高合金鋼，顧名思義，以含有合金元素的總量來(lái)加以區(qū)分，總量低于3.5%稱為低合金鋼，5～10%為中合金鋼，大于10%為高合金鋼。在國(guó)內(nèi)習(xí)慣上又將特殊質(zhì)量的碳素鋼和合金鋼稱為特殊鋼，全國(guó)31家特鋼企業(yè)專門(mén)生產(chǎn)這類鋼，如質(zhì)量碳素結(jié)構(gòu)鋼、合金結(jié)構(gòu)鋼、碳素工具鋼、合金工具鋼、高速工具鋼、碳素彈簧鋼、合金彈簧鋼、軸承鋼、不銹鋼、耐熱鋼、電工鋼，還包括高溫合金、耐蝕合金和精密合金等等。 </p> <p> 低合金鋼的出現(xiàn)可以追溯到19世紀(jì)的1870年，一種碳含量0.64～0.9%和鉻含量0.54～0.68%、抗拉強(qiáng)度685Mpa、彈性極限410Mpa鋼，被采用于工程結(jié)構(gòu)，建造了跨度158.5m的拱形橋梁。但這種鋼不理想也是十分明顯的，需要軋后熱處理，難以機(jī)械加工，耐蝕性又不良。隨后的1個(gè)多世紀(jì)的時(shí)間，世界各國(guó)不斷探索，大體上可以把低合金鋼區(qū)劃為三個(gè)不同特征的發(fā)展階段，在20世紀(jì)20年代以前，20～60年代及60年代以后。前兩個(gè)階段姑且合稱為傳統(tǒng)的低合金鋼發(fā)展階段，后一階段可以稱為現(xiàn)代低合金鋼的發(fā)展階段。

40cr是什么鋼？40cr是屬于合金結(jié)構(gòu)鋼，它是在質(zhì)量碳素結(jié)構(gòu)鋼40號(hào)的基礎(chǔ)上，適當(dāng)?shù)奶砑觕r元素，經(jīng)調(diào)質(zhì)后，具有良好的綜合性能、低溫沖擊韌度及低的缺口敏感性。40cr力學(xué)性能：抗拉強(qiáng)度：≥980mpa、屈服強(qiáng)度：≥785mpa、斷后伸長(zhǎng)率：≥9% 、斷后伸縮率：≥45% 、沖擊吸收功：≥ 47J。40cr是使用比較廣的鋼種之一，調(diào)質(zhì)處理后用于制造中速、中載的零件，如機(jī)床齒輪、軸蝸桿、花鍵軸等，調(diào)質(zhì)并高頻感應(yīng)淬火后用于制造表面高硬度、耐磨的零件，如齒輪、軸、主軸、曲軸、芯軸、套筒、銷子、連桿、螺釘、螺母、進(jìn)氣閥等。 </p> <p> <br /> </p> <p>
