</p> <p> 美國熱軋模具鋼分二大類：熱軋模具鋼，和超級熱強(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效硬化型的6H4。使用H11、H12、H13出現(xiàn)了不能滿足熱耐磨性時，可以選擇6H1，6H2，泰安模具鋼價格。 </p> <p> 當(dāng)要求模具以熱作耐磨性為主時，可以選擇D2，D4→M2，M4→粉末鋼，泰安模具鋼價格。鋼結(jié)硬質(zhì)合金，泰安模具鋼價格、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 />

H13鋼和3Cr2W8V鋼是我國目前使用廣的兩種熱作模具鋼，其中H13鋼因其良好的綜合力學(xué)性能及抗冷熱疲勞性能，能夠勝任一般模鍛工況的要求。但由于H13鋼作為中耐熱型熱作模具鋼，其工作溫度不宜超過600℃，且淬透性差不利于制造大截面模具，其應(yīng)用受到限制。 </p> <p> 3CrW8V鋼是我國較早使用且應(yīng)用廣的**熱性熱作模具鋼，其熱穩(wěn)定性良好，使用溫度可達(dá)650℃，但因其冷熱疲勞性能和導(dǎo)熱性差，容易因冷熱疲勞而產(chǎn)生龜裂甚至斷裂。而中合金DM鋼為某科研團(tuán)隊(duì)自主研發(fā)的新型熱作模具鋼?？蒲腥藛T通過3種熱鍛模具鋼熱穩(wěn)定曲線的測定及微觀組織的觀察，對比分析3種鋼熱穩(wěn)定性能的優(yōu)劣及在熱穩(wěn)定過程中微觀組織的變化。熱穩(wěn)定試驗(yàn)的試樣尺寸為10mm×10mm×15mm，采用S2-5-12箱式爐分別將試樣在580、620、650℃保溫24h，然后采用69-1型洛氏硬度計(jì)，按照GB/T230.1-2000測試不同溫度下3種試驗(yàn)鋼的洛氏硬度值。

src="https://tyunfile.71360.com/UploadFile/wxtdmj/637438965036730280/9335400.png"></div><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(dǎo)熱性。為了使模具不致積熱過多，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 /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 熱作模具鋼在工作時承受著很大的沖擊力，模腔和高溫金屬接觸，反復(fù)地加熱和冷卻，其使用條件極其惡劣。為了滿足熱作模具的使用要求，熱作模具鋼應(yīng)具備下列基本特性： </p> <p> (1)高的熱穩(wěn)定性。熱穩(wěn)定性是指鋼材在高溫下可長時間保持其常溫力學(xué)性能的能力。熱作模具工作時，接觸的是熾熱的金屬，甚至是液態(tài)金屬，所以模具表面溫度很高，一般為400～700℃。這就要求熱作模具鋼在高溫下不發(fā)生熱化，具有高的熱穩(wěn)定性，否則模具就會發(fā)生塑性變形，造成堆塌而失效。 </p> <p> <br /> </p> <p> (2)優(yōu)良的耐熱疲勞性，熱作模具的工作特點(diǎn)是反復(fù)受熱受冷，模具一時受熱膨脹，一時又冷卻收縮，形成很大的熱應(yīng)力，而且這種熱應(yīng)力是方向相反，交替產(chǎn)生的。在反復(fù)熱應(yīng)力作用下，模具表面會形成網(wǎng)狀裂紋(龜裂)，這種現(xiàn)象稱為熱疲勞，模具因熱疲勞而過早地?cái)嗔?，是熱作模具失效的主要原因之一。所以熱作模具鋼必須要有良好的熱疲勞性?</p> <p> (3)較高的高溫強(qiáng)度和良好的韌性。熱作模具，尤其是熱鍛模，工作時承受很大的沖擊力，而且沖擊頻率很高，如果模具沒有高的強(qiáng)度和良好的韌性，就容易開裂。 </p> <p> <br /> </p> <p> <br /> 無錫鐵島模具鋼材有限公司提供模具鋼，有需要可以聯(lián)系我司哦！</p><div style="width:100%;text-align:

模具鋼的硬度測試主要針對三種情況，即模具鋼材料的硬度檢測，經(jīng)過熱處理的半成品模具的檢測硬度及要求高耐磨性的模具表面熱處理后的表面硬度的檢測。供貨狀態(tài)的模具鋼主要是經(jīng)過鍛造的鋼板、鋼塊或鋼棒，一般以退火狀態(tài)供貨。某些塑料模具鋼還以預(yù)硬狀態(tài)（調(diào)質(zhì)處理）供貨，用戶可直接加工成模具而不必進(jìn)行后續(xù)熱處理。模具鋼按鋼種分類可分為碳素工具鋼、合金工具鋼和高速鋼，我國GB標(biāo)準(zhǔn)對于各種模具鋼都規(guī)定了出廠硬度要求，要求對鋼材的退火硬度和試樣淬火硬度進(jìn)行檢驗(yàn)。
