style="text-indent:25px">冷作模具鋼的工作條件及性能要求冷作模具鋼在工作時(shí)，由于被加工材料的變形抗力比較大，模具的工作部分承受很大的壓力、彎曲力、沖擊力及摩擦力。因此，冷作模具的正常報(bào)廢原因一般是磨損，也有因斷裂、崩力和變形超差而提前失效的。冷作模具鋼與刃具鋼相比，有許多共同點(diǎn)。要求模具有高的硬度和耐磨性、高的抗彎強(qiáng)度和足夠的韌性，以保證沖壓過程的順利進(jìn)行、其不同之處在于模具形狀及加I工藝復(fù)雜，而且摩擦面積大，磨損可能性大，所以修磨起來困難。因此要求具有更高的耐磨化模具工作時(shí)承受沖壓力大，又由于形狀復(fù)雜易于產(chǎn)生應(yīng)力集中，所以要求具有較高的韌性；模具尺寸大，徐州新品種模具鋼、形狀復(fù)雜，所以要求較高的淬透性，徐州新品種模具鋼、較小的變形及開裂傾向性。塑料模具用鋼要求具有一定的強(qiáng)度，徐州新品種模具鋼、硬度、耐磨性、熱穩(wěn)定性和耐蝕性等性能。徐州新品種模具鋼</p><div

style="text-indent:25px">模具鋼的耐磨性要求：決定模具使用壽命較重要的因素往往是模具材料的耐磨性。模具在工作中承受相當(dāng)大的壓應(yīng)力和摩擦力，要求模具能夠在強(qiáng)烈摩擦下仍保持其尺寸精度。模具的磨損主要是機(jī)械磨損、氧化磨損和熔融磨損三種類型。為了改善模具鋼的耐磨性，就要既保持模具鋼具有高的硬度，又要保證鋼中碳化物或其他硬化相的組成、形貌和分布比較合理。對于重載、高速磨損條件下服役的模具，要求模具鋼表面能形成薄而致密粘附性好的氧化膜，保持潤滑作用，減少模具和工件之間產(chǎn)生粘咬、焊合等熔融磨損，又能減少模具表面進(jìn)行氧化造成氧化磨損。所以模具的工作條件對鋼的磨損有較大的影響。嘉興求購熱作模具鋼熱軋模具鋼分二大類：熱軋模具鋼，和超級(jí)熱強(qiáng)合金。</p><div
