62，主要用S類和部份A類和普通的調(diào)質(zhì)鋼、彈簧鋼，南京cr12模具鋼、熱作模具或基體鋼，南京cr12模具鋼，南京cr12模具鋼。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(fù)合材料。 </p> <p> 高速鋼和超高速鋼在冷作模具中的應(yīng)用迅速增長。主要是有高的"抗壓強(qiáng)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(yīng)用相當(dāng)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(yīng)用范圍。 </p> <p> <br /> </p> <p> <br />

碳化物是絕大多數(shù)模具鋼的必需組分，除可溶于奧氏體的碳化物外，還會有部分不能溶于奧氏體的殘留碳化物。碳化物的尺寸、形態(tài)、分布對模具鋼的使用性能等有十分重要的影響。關(guān)于碳化物的尺寸、形狀和分布是與鋼的冶煉方法、鋼錠的凝固條件以及熱加工變形條件等有關(guān)。過共析鋼的碳化物可能在晶界形成風(fēng)狀碳化物或是在加工變形中碳化物被拉長而形成帶狀碳化物或者二者兼有，萊氏體模具鋼中，存在一次碳化物和二次碳化物，在熱變形的過程中，網(wǎng)狀的共晶碳化物大多可以破碎，碳化物先沿變形方向延伸，產(chǎn)生帶狀，隨著變形程度的增加，碳化物變得均勻、細(xì)小。碳化物的不均勻性對淬火變形、開裂、鋼材的力學(xué)性能的影響較大。

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 /> 無錫鐵島模具鋼材有限公司提供模具鋼，有想法可以來我司咨詢！日照SKD61模具鋼</p><p

在模具生產(chǎn)成本中，材料費(fèi)用一般占10%~20%，而機(jī)械加工、熱處理、裝配和管理費(fèi)用占80%以上，所以模具材料的工藝性能是影響模具的生產(chǎn)成本和制造難易的主要因素之一?？杉庸ば浴獰峒庸ば阅?，指熱塑性、加工溫度范圍等；——冷加工性能，指切削、磨削、拋光、冷拔等加工性能。 </p> <p> 冷作模具鋼大多屬于過共析鋼和萊氏體鋼，熱加工和冷加工性能都不太好，因此必須嚴(yán)格控制熱加工和冷加工的工藝參數(shù)，以避免產(chǎn)生缺陷和廢品。另一方面，通過提高鋼的純凈度，減少有害雜質(zhì)的含量，改善鋼的組織狀態(tài)，以改善鋼的熱加工和冷加工性能，從而降低模具的生產(chǎn)成本。 </p> <p>
