H13鋼是使用*****和相當(dāng)有**性的熱作模具鋼種，它的主要特性是：（1）具有高的淬透性和高的韌性；（2）優(yōu)良的抗熱裂能力，在工作場(chǎng)合可予以水冷；（3）具有中等耐磨損能力，還可以采用滲碳或滲氮工藝來提高其表面硬度，但要略為降低抗熱裂能力；（4）因其含碳量較低，回火中二次硬化能力較差；（5）在較高溫度下具有抗軟化能力，但使用溫度高于540℃（1000℉）硬度出現(xiàn)迅速下降（即能耐的工作溫度為540℃）；（6）熱處理的變形??；（7）中等和高的切削加工性；（8）中等抗脫碳能力。更為令人注意的是，它還可用于制作航空工業(yè)上的重要構(gòu)件。H13鋼是C-Cr-Mo-Si-V型鋼，在世界上的應(yīng)用極其普遍,同時(shí)各國(guó)許多學(xué)者對(duì)它進(jìn)行了***的研究，并在探究化學(xué)成分的改進(jìn)。鋼的應(yīng)用***和具有優(yōu)良的特性，主要由鋼的化學(xué)成分決定的。當(dāng)然鋼中雜質(zhì)元素必須降低，有資料表明，當(dāng)Rm在1550MPa時(shí)，材料含硫量由，會(huì)使沖擊韌度提高約13J。NADCA207-2003標(biāo)準(zhǔn)就規(guī)定：優(yōu)級(jí)(premium)H13鋼含硫量小于，而超級(jí)(superior)的應(yīng)小于。

style="text-indent:25px">合金圓鋼性能分析：金屬在大氣中都可與氧氣反響在外表構(gòu)成氧化膜，普通碳鋼上構(gòu)成的氧化鐵會(huì)繼續(xù)停止氧化，使銹蝕不時(shí)擴(kuò)展，結(jié)果構(gòu)成孔洞。這能夠應(yīng)用油漆或耐氧化的金屬停止電鍍來維護(hù)碳鋼外表，但這種維護(hù)層只是一種薄膜，假如維護(hù)層被毀壞，下面的鋼便又開端銹蝕。合金圓鋼能否被銹蝕與鋼中的鉻含量有關(guān)，鋼中的鉻含量到達(dá)12%時(shí)，在大氣中，合金圓鋼外表生成了一層鈍化的、致密的富鉻氧化物而維護(hù)外表，可避免進(jìn)一步再氧化。這種氧化層極薄，透過它能夠看到鋼外表的自然光澤，使合金具有共同的外表。假如鉻膜一旦毀壞，鋼中的鉻與大氣中的氧重重生成鈍化膜，繼續(xù)起維護(hù)作用。在一些特殊環(huán)境下，合金也會(huì)呈現(xiàn)某些部分腐蝕而失效，但合金與碳鋼不同，不會(huì)呈現(xiàn)平均腐蝕而失效，因而腐蝕余量對(duì)合金圓鋼來說沒有意義。衡水圓鋼生產(chǎn)廠家</p></p><br
