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(lái)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。合金圓鋼經(jīng)過(guò)不斷的發(fā)展，在很多方面都得到了比較好的應(yīng)用。</p><div
