模具鋼是用來制造冷沖模、熱鍛模、壓鑄模等模具的鋼種。模具是機械制造、無線電儀表、電機、電器等工業(yè)部門中制造零件的主要加工工具。模具的質量直接影響著壓力加工工藝的質量、產品的精度產量和生產成本，而模具的質量與使用壽命除了靠合理的結構設計和加工精度外，主要受模具材料和熱處理的影響。模具鋼大致可分為：冷軋模具鋼、熱軋模具鋼和塑料模具鋼三類，用于鍛造、沖壓、切型、壓鑄等。由于各種模具用途不同，工作條件復雜，因此對模具用鋼，按其所制造模具的工作條件，應具有高的硬度、強度、耐磨性，足夠的韌性，以及高的淬透性、淬硬性和其他工藝性能。由于這類用途不同，工作條件復雜，因此對模具用鋼的性能要求也不同。

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。模具鋼的化學成分，晶粒度，純凈度，碳化物和夾雜物等的數量、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、強度和韌性達到很好的配合。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </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> ◆時效鋼是經過時效處理而獲得高的使用性能。有兩種，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經滲碳淬火后使用。腐蝕性強用420。 </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。 </p> <p> <br /> </p> <p> <br /> 無錫鐵島模具鋼材有限公司可大量供應模具鋼歡迎咨詢。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

（1）模腔表層金屬產生熱疲勞（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、空氣等介質冷卻模腔的表面。因此．熱模的工作狀態(tài)是反復受熱和冷卻，從而使模腔表層金屬產生反復的熱脹冷縮，即反復承受拉壓應力作用．其結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鋼的導熱性。鋼的導熱性高，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。一般認為鋼的導熱性與合碳量有關，含碳量高時導熱性低，所以熱作模具鋼不宜采用高碳鋼。在生產中通常采用中碳鋼（C0.3%5～0.6%）合碳量過低．會導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。

深冷處理對鋼材的作用性： </p> <p> 1）超深冷能提高DC53模具鋼模具鋼及DY-SKH51高速鋼的硬度，韌性得到更充分的保證（在超深冷過程中是殘余碳化物轉變?yōu)轳R氏體）。 </p> <p> 2）超深冷也能讓DC53模具鋼模具工件具有精度保持性（尺寸穩(wěn)定性），防止在室溫因殘留奧氏體轉變而發(fā)生尺寸變化。 </p> <p> 3）深冷處理也能促使未轉變的奧氏體更多地轉變成馬氏體，進一步提高硬度，從而提高零件的耐磨性和使用壽命；促進微細碳化物的彌散析出，可以DC53模具鋼圓鋼的韌性。 </p> <p> <br /> </p> <p> <br /> 合肥CR12MOV模具鋼</p><p style="text-indent:25px">無錫鐵島模具鋼材有限公司總部位于梅村新都路5號，是一家無錫鐵島模具鋼材有限公司主營P20
