<br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 由于熱作模具鋼工作條件的特點，因此會帶來以下方面的問題： </p> <p> （1）模腔表層金屬產(chǎn)生熱疲勞（龜裂）。熱作模具的工作特點是具有間歇性．每次使熱態(tài)金屬成形后都要用水、油、空氣等介質(zhì)冷卻模腔的表面。因此．熱模的工作狀態(tài)是反復(fù)受熱和冷卻，從而使模腔表層金屬產(chǎn)生反復(fù)的熱脹冷縮，即反復(fù)承受拉壓應(yīng)力作用．其結(jié)果引起模腔表面出現(xiàn)龜裂，稱為熱疲勞現(xiàn)象，由此，對熱模具鋼提出了第二個基本使用性能要求．即具有高的熱疲勞抗力。一般說來，影響鋼的熱疲勞抗力的因素主要有：①鋼的導(dǎo)熱性。鋼的導(dǎo)熱性高，可使模具表層金屬受熱程度降低，從而減小鋼的熱疲勞傾向性。一般認為鋼的導(dǎo)熱性與合碳量有關(guān)，含碳量高時導(dǎo)熱性低，所以熱作模具鋼不宜采用高碳鋼。在生產(chǎn)中通常采用中碳鋼（C0.3%5～0.6%）合碳量過低．會導(dǎo)致鋼的硬度和強度下降．也是不利的。②鋼的臨界點影響。通常鋼的臨界點（Acl）越高．鋼的熱疲勞傾向性越低。因此．一般通過加入合金元素Cr、W、Si、引來提高鋼的臨界點。從而提高鋼的熱疲勞抗。

<p> 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鋼的韌性帶來很大的影響。特別是鋼的純凈度和熱加工變形情況對于其橫向韌性的影響更為明顯。鋼的韌性、強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、強度和韌性達到配合。 </p> <p> 沖擊韌性系表特征材料在一次沖擊過程中試樣在整個斷裂過程中吸收的總能量。但是很多工具是在不同工作條件下疲勞斷裂的，因此，常規(guī)的沖擊韌性不能反映模具鋼的斷裂性能。小能量多次沖擊斷裂功或多次斷裂壽命和疲勞壽命等試驗技術(shù)正在被采用。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 美國是早在工具鋼中列出塑料模具**鋼的國家，以P來表示為主，共分為五類。 </p> <p> ◆ 滲碳型塑料模具鋼：P1，P2，P3，P4，P5，P6。這類鋼含碳量很低，主要是美國早期及用擠壓成型制模法，要求冷塑性好，有高的擠壓性能，成型后表面滲碳淬火提高表面硬度，使用壽命長。 </p> <p> ◆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)時使用。 </p> <p> ◆ 中碳合金工具鋼用于熱固性塑料模。鋼號有H13，而L2和S7，O1和A2也有應(yīng)用。這一類的特點是： </p> <p> （1）基本屬二次硬化金鋼，500-600oC時的熱強性好。 </p> <p> （2）含鉻較高，大氣腐蝕性好。 </p> <p> （3）淬透性極好，適用于大模塊。 </p> <p> ◆不銹鋼用于耐蝕性要求高的塑料模，主要鋼號有420，414L，440，416。 </p> <p> <br /> </p> <p> <br /> 模具鋼質(zhì)量過硬，歡迎咨詢無錫鐵島模具鋼材有限公司了解！</p><div style="width:100%;text-align:

耐磨性可用模擬的試驗方法，測出相對的耐磨指數(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)。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大的壓應(yīng)力和摩擦力，要求模具能夠在強烈摩擦下仍保持其尺寸精度。模具的磨損主要是機械磨損、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行氧化造成氧化磨損。所以模具的工作條件對鋼的磨損有較大的影響。

模具鋼深冷處理工藝是怎樣的？深冷處理的作用性非常大，近期有很多客戶來咨詢模具鋼深冷處理工藝，模具鋼深冷處理溫度等等之類的問題，天成模具小編在這里為大家詳細解答下，模具鋼深冷處理工藝是怎樣的。模具鋼深冷處理一般在零下196℃進行。DC53模具鋼板材深冷正常的處理工藝如下：一般在淬火和回火工序之間進行，也能在淬火回火之后進行深冷處理。但是有一種情況要注意，如果在淬火、回火后鋼中仍保留有殘余奧氏體，則在深冷處理后仍需要再進行一次回火。深冷處理能提高鋼的耐磨性和抗回火穩(wěn)定性。深冷處理不僅用于冷作模具，也可用于熱作模具和硬質(zhì)合金。
