熱作模具鋼的特性：3Cr3Mo3W2V代號HM1，1970年代研制的HM1鋼，在熱穩(wěn)定性、抗熱疲勞性等方面均有所提高，該鋼種已納入GB 1299—85的國家標準模具鋼號，它具有良好的抗熱疲勞性能、抗回火穩(wěn)定性能和良好的冶煉、鍛造，淮北NAK80模具鋼、熱處理及機械加工工藝性能，是國內(nèi)綜合性能優(yōu)良、符合我國資源條件的**韌性熱作模具新鋼種，在高溫性能方面明顯優(yōu)于H13鋼。熱作模具鋼的應用實例： </p> <p> （1）鋁和銅合金壓鑄模、熱擠壓模具等，使用壽命可比3Cr2W8V提高1～4倍，淮北NAK80模具鋼。 </p> <p> （2）適用于高溫、高負荷、急熱急冷條件下的壓力機鍛模、軸承熱鍛凹模、成型滾鍛模。 </p> <p> （3）**度和高熱強鋼的精密鍛造模。熱作模具鋼具有優(yōu)良的強韌性、較高熱強性、耐磨性、回火穩(wěn)定性、耐冷熱疲勞性能，冷熱加工性能好，工作溫度700℃以上，該鋼通用性強，淮北NAK80模具鋼。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br />

通常錘鍛模工作時．其模腔表面溫度可達300～400℃以上熱擠壓模可達500一800℃以上；壓鑄模模腔溫度與壓鑄材料種類及澆注溫度有關。如壓鑄黑色金屬時模腔溫度可達1000℃以上。這樣高的使用溫度會使模腔表面硬度和強度明顯降低，在使用中易發(fā)生打垛。為此．對熱作模具鋼的基本使用性能要求是熱塑變抗力高，包括高溫硬度和高溫強度、高的熱塑變抗力，實際上反映了鋼的高回火穩(wěn)定性。由此便可以找到熱模具鋼合金化的第一種途徑，即加入Cr、W、Si．等合金元素可以提高鋼的回火穩(wěn)定性。

在工作過程中，模具承受著沖擊載荷，為了減少在使用過程中的折斷、崩刃等形式的損壞，要求模具鋼具有一定的韌性。 </p> <p> 模具鋼的化學成分，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正在被采用。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 模具鋼發(fā)展前景預測： </p> <p> 2016年以來中國家電業(yè)產(chǎn)品銷售量增速放緩。隨著國家產(chǎn)業(yè)升級調(diào)整政策的推行，2017年中國家電業(yè)有望平穩(wěn)度過市場平淡期，站上歷史的新高點。預計至2023年，我國主要家電對模具的需求將超過千億副。 </p> <p> 由上所述，現(xiàn)階段我國模具鋼供需缺口龐大，需要從日本、德國、瑞典等國家進口大量的模具鋼，主要是因為國外模具鋼能夠很大延長模具的使用壽命。盡管如此，國產(chǎn)的模具鋼有著國外鋼廠不可比擬的優(yōu)勢：一是交貨時間優(yōu)勢；二是成本優(yōu)勢，對于同樣規(guī)格的產(chǎn)品，國產(chǎn)模具鋼價格只有國外的1/5到1/3。近年來，我國的模具鋼生產(chǎn)工藝和技術已經(jīng)取得了長足的進步，隨著技術的進一步成熟，國內(nèi)的模具鋼產(chǎn)品將逐漸替代進口產(chǎn)品。到2023年，我國模具鋼行業(yè)市場規(guī)模將超過500億美元。

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除受到毛坯變形時產(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)良好的導熱性。為了使模具不致積熱過多，導致力學性能下降，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，為了使整個模具截面的力學性能均勻，這就要求熱作模具鋼有高的淬透性能。 </p> <p> <br /> </p> <p> <br /> 想要購買模具鋼，就選無錫鐵島模具鋼材有限公司，讓您滿意，歡迎您的來電哦！淮北NAK80模具鋼</p><p

（1）硬度硬度是模具鋼的主要技術指標，模具在高應力的作用下欲保持其形狀尺寸不變，必須具有足夠高的硬度。冷作模具鋼在室溫條件下一般硬度保持在HRC60左右，熱作模具鋼根據(jù)其工作條件，一般要求保持在HRC40~55范圍。對于同一鋼種而言，在一定的硬度值范圍內(nèi)，硬度與變形抗力成正比；但具有同一硬度值而成分及組織不同的鋼種之間，其塑性變形抗力可能有明顯的差別。 </p> <p> （2）紅硬性在高溫狀態(tài)下工作的熱作模具，要求保持其組織和性能的穩(wěn)定，從而保持足夠高的硬度，這種性能稱為紅硬性。碳素工具鋼、低合金工具鋼通常能在180~250℃的溫度范圍內(nèi)保持這種性能，鉻鉬熱作模具鋼一般在550~600℃的溫度范圍內(nèi)保持這種性能。鋼的紅硬性主要取決于鋼的化學成分和熱處理工藝。 </p> <p> <br /> </p> <p> <br />
