style="text-indent:25px">使鋼具有高硬度、高耐磨，其硬度與耐磨性要高于鉬鉻鑄鐵。其含有的釩能細(xì)化晶粒增加韌度，又能形成高硬度的VC，以進(jìn)一步增加鋼的耐磨性;鉻又使鋼具有高的淬透性和回火穩(wěn)定性。經(jīng)整體淬火后，需要1～2次的回火，熱處理時(shí)間較長(zhǎng)?；鸷笥捕瓤梢赃_(dá)到HRC 60-62。但熱處理后變形量要大于空冷鋼，消除變形困難，容易降低模具的精度。生產(chǎn)Cr12MoV模具鋼的方法為鍛造，生產(chǎn)成本較高，同時(shí)由于鍛造工藝的局限性，Cr12MoV鋼只能分塊鍛造，制造模具時(shí)還需要拼裝鑲塊，增加了鉗工的勞動(dòng)強(qiáng)度，延長(zhǎng)了模具的制造周期，成本也隨之增加。汽車模具與沖壓線機(jī)床噸位和工作臺(tái)面基本匹配，暫不需改善。</p><div
