塑料模具鋼Cr12Mov這是在塑料行業快速的發展下產生的物品，對于精度的要求是越來越高了，性能也在一步步的要求完美，尺寸的需求也更多了。
      塑料模具(ju)用(yong)鋼要(yao)求具(ju)有(you)(you)一(yi)定的(de)強度(du)(du)(du)、硬(ying)度(du)(du)(du)、耐磨(mo)性(xing)(xing)(xing)(xing)、熱(re)(re)穩(wen)定性(xing)(xing)(xing)(xing)和耐蝕性(xing)(xing)(xing)(xing)等(deng)性(xing)(xing)(xing)(xing)能(neng)。此外(wai)，還(huan)要(yao)求具(ju)有(you)(you)良好(hao)的(de)工(gong)藝性(xing)(xing)(xing)(xing)，如熱(re)(re)處理變形(xing)(xing)(xing)小、加工(gong)性(xing)(xing)(xing)(xing)能(neng)好(hao)、耐蝕性(xing)(xing)(xing)(xing)好(hao)、研磨(mo)和拋光性(xing)(xing)(xing)(xing)能(neng)好(hao)、補焊性(xing)(xing)(xing)(xing)能(neng)好(hao)、粗糙度(du)(du)(du)高、導熱(re)(re)性(xing)(xing)(xing)(xing)好(hao)和工(gong)作條(tiao)件尺(chi)寸和形(xing)(xing)(xing)狀穩(wen)定等(deng)。一(yi)般情況下，注射(she)成(cheng)(cheng)形(xing)(xing)(xing)或擠壓成(cheng)(cheng)形(xing)(xing)(xing)模具(ju)可選用(yong)熱(re)(re)作模具(ju)鋼；熱(re)(re)固性(xing)(xing)(xing)(xing)成(cheng)(cheng)形(xing)(xing)(xing)和要(yao)求高耐磨(mo)、高強度(du)(du)(du)的(de)模具(ju)可選用(yong)冷作模具(ju)鋼。
