淬透性主要取決于鋼的化學(xué)成分和淬火前的原始組織狀態(tài)；淬硬性則主要取決于鋼中的含碳量。對(duì)于大部分的冷作模具鋼，淬硬性往往是主要的考慮因素之一。對(duì)于熱作模具鋼和塑料模具鋼，一般模具尺寸較大，尤其是制造大型模具，其淬透性更為重要。另外，對(duì)于形狀復(fù)雜容易產(chǎn)生熱處理變形的各種模具，為了減少淬火變形，往往盡可能采用冷卻能力較弱的淬火介質(zhì)，如空冷、油冷或鹽浴冷卻，為了得到要求的硬度和淬硬層深度，就需要采用淬透性較好的模具鋼。 [2] </p> <p> 淬火溫度和熱處理變形 </p> <p> 為了便于生產(chǎn)，要求模具鋼淬火溫度范圍盡可能放寬一些，特別是當(dāng)模具采用火焰加熱局部淬火時(shí)，由于難于準(zhǔn)確地測(cè)量和控制溫度，就要求模具鋼有更寬的淬火溫度范圍。 </p> <p>

決定模具使用壽命重要的因素往往是模具材料的耐磨性。模具在工作中承受相當(dāng)大的壓應(yīng)力和摩擦力，要求模具能夠在強(qiáng)烈摩擦下仍保持其尺寸精度。模具的磨損主要是機(jī)械磨損、氧化磨損和熔融磨損三種類型。為了改善模具鋼的耐磨性，就要既保持模具鋼具有高的硬度，又要保證鋼中碳化物或其他硬化相的組成、形貌和分布比較合理。對(duì)于重載、高速磨損條件下服役的模具，要求模具鋼表面能形成薄而致密粘附性好的氧化膜，保持潤(rùn)滑作用，減少模具和工件之間產(chǎn)生粘咬、焊合等熔融磨損，又能減少模具表面進(jìn)行氧化造成氧化磨損。所以模具的工作條件對(duì)鋼的磨損有較大的影響。 </p> <p> 耐磨性可用模擬的試驗(yàn)方法，測(cè)出相對(duì)的耐磨指數(shù)，作為表征不同化學(xué)成分及組織狀態(tài)下的耐磨性水平的參數(shù)。以呈現(xiàn)規(guī)定毛刺高度前的壽命，反映各種鋼種的耐磨水平；試驗(yàn)是以Cr12MoV鋼為基準(zhǔn)進(jìn)行對(duì)比。 </p> <p> <br /> </p> <p> <br

模具鋼材的硬度如何檢測(cè)？硬度是模具鋼重要的性能之一，對(duì)于快速、精確地測(cè)試模具鋼材硬度在模具制造和使用單位是非常關(guān)鍵的。同時(shí)也具有十分重要的意義，它可以提升模具質(zhì)量、制造水平和延長(zhǎng)模具的使用壽命。模具鋼是模具工業(yè)的主體材料，根據(jù)模具的服役條件、環(huán)境和狀態(tài)的不同，模具鋼應(yīng)具備不同的特性。在工業(yè)生產(chǎn)中，模具使用壽命和制成零件的精度、質(zhì)量、外觀性能，除與模具的設(shè)計(jì)技術(shù)、制造精度，以及機(jī)床精度和制造操作有關(guān)外，正確地選用模具材料和正確地執(zhí)行熱處理工藝也是至關(guān)重要的，資料顯示，模具早期失效因材料選擇不當(dāng)和材料內(nèi)部缺陷引起的大約占百分之十左右，而由熱處理不當(dāng)引起的約占百分之四十九。硬度是模具材料和成品模具的重要性能指標(biāo)。模具在工作時(shí)的受力狀態(tài)是復(fù)雜的，如熱作模具通常是在交變的溫度場(chǎng)下承受交變應(yīng)力作用，因此它應(yīng)具有良好的阻止模具轉(zhuǎn)變成較軟或塑性狀態(tài)的能力，并且在長(zhǎng)期工作環(huán)境下仍保持模具的形狀和尺寸精度不變。一般成品模具的硬度，冷作模具常選擇在59至60HRC，熱作模具常選擇在48HRC左右。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 熱作模具鋼基本特性：(4)良好的耐磨性能，由于熱作模具制作時(shí)除受到毛坯變形時(shí)產(chǎn)生摩擦磨損之外，還受到高溫氧化腐蝕和氧化鐵屑的研磨，所以需要熱作模具鋼有較高的硬度和抗黏附性。 </p> <p> (5)良好的導(dǎo)熱性。為了使模具不致積熱過(guò)多，導(dǎo)致力學(xué)性能下降，要盡可能降低模面溫度，減小模具內(nèi)部的溫差，這就要求熱作模具鋼要有良好的導(dǎo)熱件能。 </p> <p> (6)良好的成形加工工藝性能，以滿足加工成形的需要。 </p> <p> (7)高淬透性。熱作模具鋼一般尺寸比較大，熱鍛模尤其是這樣，為了使整個(gè)模具截面的力學(xué)性能均勻，這就要求熱作模具鋼有高的淬透性能。 </p> <p> <br /> </p> <p> <br /> 無(wú)錫鐵島模具鋼材有限公司可大量供應(yīng)模具鋼歡迎咨詢。</p><div style="width:100%;text-align: center;"><img

</p> <p> 選擇冷作模具鋼的一種基本方法是：先把除磨損外的其他失效機(jī)理全部排除，然后選擇具備適合耐磨損性的工具鋼，以滿足產(chǎn)品生產(chǎn)量的要求。如何對(duì)工具鋼的磨損判定？必須從被加工材料類型、被加工材料硬度、被加工材料是否有顆粒存在，這幾個(gè)方面判定其抗磨損能力。冷作模具鋼**擁有鋼材性能方面的知識(shí)是遠(yuǎn)遠(yuǎn)不夠的，還必須考慮生產(chǎn)零件的數(shù)量、被加工材料的類型、厚度及其硬度等因素。高生產(chǎn)數(shù)量有時(shí)需要不只一副模具才能滿足產(chǎn)量需求，因此，需要高壽命的工具鋼，以達(dá)到模具整體經(jīng)濟(jì)效益；另外，低產(chǎn)量要求的模具可使用合金工具鋼。
