就國(guó)內(nèi)外使用的模具鋼材而言，模具鋼密度一般都在7.85左右，通常模具鋼是鍛造件，密度在8000-8400千克/立方米。不同模具鋼材中加入的合金元素比例不一樣，模具鋼密度會(huì)有小范圍的差別。 </p> <p> 密度是物質(zhì)的特性之一，每種物質(zhì)都有一定的密度，不同物質(zhì)的密度一般是不同。因此我們可以利用密度來(lái)鑒別物質(zhì)。所以我們可以根據(jù)密度公式ρ=M/V，計(jì)算出任意一種模具鋼的密度。 </p> <p> 根據(jù)密度公式：ρ=m/v，也就是說(shuō)決定模具鋼質(zhì)量和體積的因素決定了模具鋼密度。那么從微觀的角度來(lái)講的話，就是分子量和分子間隙共同決定物質(zhì)的密度。體積、大小、質(zhì)量、壓強(qiáng)、壓力和溫度影響物質(zhì)密度，高速鋼模具鋼廠家，雖然物質(zhì)密度物質(zhì)的本身屬性，它是一定的，但是物質(zhì)有各種狀態(tài)，當(dāng)物質(zhì)形成態(tài)的轉(zhuǎn)化的時(shí)候，高速鋼模具鋼廠家，密度才會(huì)變化。比如水，高速鋼模具鋼廠家，升溫可導(dǎo)致水的氣化，密度變小，加壓又可以使水蒸氣從新凝結(jié)為液態(tài)水，密度變大。 </p> <p> <br /> </p> <p> <br /> 想要購(gòu)買(mǎi)模具鋼，歡迎咨詢(xún)無(wú)錫鐵島模具鋼材有限公司了解！高速鋼模具鋼廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

熱作模具鋼在服役條件下除了承受載荷的周期性變化之外，還受到高溫及周期性的急冷急熱的作用，因此，評(píng)價(jià)熱作模具鋼的斷裂抗力應(yīng)重視材料的熱機(jī)械疲勞斷裂性能。熱機(jī)械疲勞是一種綜合性能的指標(biāo)，它包括熱疲勞性能、機(jī)械疲勞裂紋擴(kuò)展速率和斷裂韌性三個(gè)方面。 </p> <p> 熱疲勞性能反映材料在熱疲勞裂紋萌生之前的工作壽命，抗熱疲勞性能高的材料，萌生熱疲勞裂紋的熱循環(huán)次數(shù)較多；機(jī)械疲勞裂紋擴(kuò)展速率反映材料在熱疲勞裂紋萌生之后，在鍛壓力的作用下裂紋向內(nèi)部擴(kuò)展時(shí)，每一應(yīng)力循環(huán)的擴(kuò)展量；斷裂韌性反映材料對(duì)已存在的裂紋發(fā)生失穩(wěn)擴(kuò)展的抗力。斷裂韌性高的材料，其中的裂紋如要發(fā)生失穩(wěn)擴(kuò)展，必須在裂紋前端具有足夠高的應(yīng)力強(qiáng)度因子，也就是必須有較大的裂紋長(zhǎng)度。在應(yīng)力恒定的前提下，在一種模具中已經(jīng)存在一條疲勞裂紋，如果模具材料的斷裂韌性值較高，則裂紋必須擴(kuò)展得更深，才能發(fā)生失穩(wěn)擴(kuò)展。 </p> <p> 也就是說(shuō)，抗熱疲勞性能決定了疲勞裂紋萌生前的那部分壽命；而裂紋擴(kuò)展速率和斷裂韌性，可以決定當(dāng)裂紋萌生后發(fā)生亞臨界擴(kuò)展的那部分壽命。因此，熱作模具如要獲得高的壽命，模具材料應(yīng)具備高的抗熱疲勞性能、低的裂紋擴(kuò)展速率和高的斷裂韌性值。 </p> <p> <br /> </p> <p> <br />

◆調(diào)質(zhì)型塑料模具：P20，P21。塑料模具中P20的用量很大，已成為主體，大多數(shù)在預(yù)硬狀態(tài)時(shí)使用。 </p> <p> ◆ 中碳合金工具鋼用于熱固性塑料模。鋼號(hào)有H13，而L2和S7，O1和A2也有應(yīng)用。這一類(lèi)的特點(diǎn)是： </p> <p>

美國(guó)熱軋模具鋼分二大類(lèi)：熱軋模具鋼，和超級(jí)熱強(qiáng)合金。 </p> <p> 熱軋模具由于在有溫度的條件下工作，要求材料具有熱強(qiáng)性和熱耐磨性，為了保證模具的使用壽命模具要冷卻，熱冷交替模具會(huì)出現(xiàn)龜裂，即熱疲勞裂紋，所以材料又要求有抗裂紋能力和抗熱疲勞性能。 </p> <p> 按熱強(qiáng)性排列的主系列進(jìn)行選材: </p> <p> 低合金調(diào)質(zhì)模具鋼（6G，6F2，6F3）→中鉻熱作模具鋼（H11、H12、H13）→鎢熱作模具鋼（H21，H22）。 </p> <p> 非標(biāo)準(zhǔn)的熱作模具鋼：例如熱鐓鍛模具用時(shí)效硬化型的6H4。使用H11、H12、H13出現(xiàn)了不能滿足熱耐磨性時(shí)，可以選擇6H1，6H2。 </p> <p> 當(dāng)要求模具以熱作耐磨性為主時(shí)，可以選擇D2，D4→M2，M4→粉末鋼。鋼結(jié)硬質(zhì)合金、鈷基硬質(zhì)合金的高溫耐磨性是很高的，但其熱疲勞性（即冷熱抗疲勞裂紋）很差，不能在急冷急熱狀態(tài)下使用。 </p> <p> <br /> </p> <p> <br />

在工作過(guò)程中，模具承受著沖擊載荷，為了減少在使用過(guò)程中的折斷、崩刃等形式的損壞，要求模具鋼具有一定的韌性。模具鋼的化學(xué)成分，晶粒度，純凈度，碳化物和夾雜物等的數(shù)量、形貌、尺寸大小及分布情況，以及模具鋼的熱處理制度和熱處理后得到的金相組織等因素都對(duì)鋼的韌性帶來(lái)很大的影響。特別是鋼的純凈度和熱加工變形情況對(duì)于其橫向韌性的影響更為明顯。鋼的韌性、強(qiáng)度和耐磨性往往是相互矛盾的。因此，要合理地選擇鋼的化學(xué)成分并且采用合理的精煉、熱加工和熱處理工藝，以使模具材料的耐磨性、強(qiáng)度和韌性達(dá)到很好的配合。
