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> ◆時效鋼是經(jīng)過時效處理而獲得高的使用性能。有兩種，P20模具鋼加工，一種是P21低碳Ni-A1時效鋼；另一類是18Ni馬氏體時效鋼。后者是用于宇航工業(yè)的無碳高純度、**度、高韌性的材料。用于力學性能、尺寸精度、光潔度和耐蝕性都要求高的塑料模具中。 </p> <p> 塑料模具鋼的選用 </p> <p> 薄壁的塑料箱體，生產(chǎn)批量在小于10萬件時，用P20，P21預硬態(tài)（HB250～300），腐蝕性較強時用414L。 </p> <p> 高壽命的普通塑料模，用P6或P20，經(jīng)滲碳一淬火后硬度在HRC54-58；塑料件不太大時，可用O1，S7。腐蝕性較強時用420。 </p> <p> 非高溫的熱固性模用P6，P20經(jīng)滲碳淬火后使用。腐蝕性強用420，P20模具鋼加工。 </p> <p> 高溫熱固性塑料模用H13和S7或滲碳鋼P4。這些含鉻較高有好的抗回火性和抗高溫氧化性，P20模具鋼加工。 </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，用戶的信賴之選。P20模具鋼加工</p><div

洛氏硬度計可以用于模具鋼材的硬度檢測，供貨狀態(tài)的模具鋼硬度在187至285HBS之間，可以用洛氏硬度計的HRB及HRC標尺來測試。測試后經(jīng)查表將洛氏硬度值換算成布氏硬度值，仍然具有相當高的精度。這種洛氏硬度計也是采用了一個C型架結(jié)構(gòu)，C型架開口尺寸為200mm和500mm，模具鋼的厚度只要小于這個尺寸就可以測試，儀器測試精度可以達到1.0HRC，換算成布氏硬度的誤差大約是5至7HBS。完成了機械加工的模具鋼材料要進行淬火回火處理，再經(jīng)過精磨和拋光就可成為成品模具。淬火回火處理后的模具硬度檢測更為重要，因為這時的材料硬度是一個非常重要的質(zhì)量指標，它在很大程度上決定了成品模具的使用壽命。

src="https://tyunfile.71360.com/UploadFile/wxtdmj/637438965201868005/5793540.png"></div><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是反復受熱受冷，模具一時受熱膨脹，一時又冷卻收縮，形成很大的熱應力，而且這種熱應力是方向相反，交替產(chǎn)生的。在反復熱應力作用下，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斷裂，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度和良好的韌性，就容易開裂。 </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 /> 想要質(zhì)量好的模具鋼，請找無錫鐵島模具鋼材有限公司！</p><div

<br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 冷軋模具鋼的選用 </p> <p> 冷軋模具鋼的主系列是高硬冷作類，主要用于要求高抗壓和耐磨為主的模具，硬度高于HRC60-62。對于要求耐沖擊、韌性高的模具，硬度低于HRC60- 62，主要用S類和部份A類和普通的調(diào)質(zhì)鋼、彈簧鋼、熱作模具或基體鋼。對于大型沖壓模，如汽車外型沖壓件，主要用鑄鐵類。簡易或壽命數(shù)量少的用鋅基合金或高分子復合材料。 </p> <p> 高速鋼和超高速鋼在冷作模具中的應用迅速增長。主要是有高的"抗壓強度/硬度" 比值。且硬度可在HRC60-70之間選擇。 </p> <p> 粉末模具鋼有優(yōu)良的耐磨壽命，硬度不大高HRC60-62，應用相當多。 </p> <p> 碳素工具鋼在壽命10萬件的沖頭或軟材料沖壓模仍有一定的應用范圍。 </p> <p> <br /> </p> <p> <br /> 無錫鐵島模具鋼材有限公司提供模具鋼，有想法的不要錯過哦！鹽城NAK80模具鋼</p><p
