（1）硬度硬度是模具鋼的主要技術指標，模具在高應力的作用下欲保持其形狀尺寸不變，必須具有足夠高的硬度。冷作模具鋼在室溫條件下一般硬度保持在HRC60左右，熱作模具鋼根據(jù)其工作條件，一般要求保持在HRC40~55范圍。對于同一鋼種而言，在一定的硬度值范圍內，硬度與變形抗力成正比；但具有同一硬度值而成分及組織不同的鋼種之間，其塑性變形抗力可能有明顯的差別。 </p> <p> （2）紅硬性在高溫狀態(tài)下工作的熱作模具，要求保持其組織和性能的穩(wěn)定，從而保持足夠高的硬度，這種性能稱為紅硬性。碳素工具鋼、低合金工具鋼通常能在180~250℃的溫度范圍內保持這種性能，鉻鉬熱作模具鋼一般在550~600℃的溫度范圍內保持這種性能。鋼的紅硬性主要取決于鋼的化學成分和熱處理工藝。 </p> <p> <br /> </p> <p> <br />

塑料模具鋼包括熱塑性塑料模具和熱固性塑料模具。美國是較早在工具鋼中列出塑料模具**鋼的國家，塑料模具用鋼要求具有一定的強度、硬度、耐磨性、熱穩(wěn)定性和耐蝕性等性能。此外，還要求具有良好的工藝性，如熱處理變形小、加工性能好、耐蝕性好、研磨和拋光性能好、補焊性能好、粗糙度高、導熱性好和工作條件尺寸和形狀穩(wěn)定等。一般情況下，注射成形或擠壓成形模具可選用熱作模具鋼；熱固性成形和要求高耐磨、**度的模具可選用冷作模具鋼。

偏析即鋼的成分與組織不均勻性的表現(xiàn)，這是在模具鋼的低倍組織的檢驗中常存在的一種缺陷。是鋼錠在凝固過程中形成的，與鋼的化學成分和澆注溫度等有關。一般分為樹枝狀的偏析、方形偏析、點狀偏析等。由于樹枝狀的偏析的存在，使負然各個不同的方向的力學性能表現(xiàn)出明顯的差異。方形偏析是由于鑄錠結晶時，在柱狀晶的末端與錠心等軸晶區(qū)間，聚集了較多的雜質和孔隙而形成的。嚴重的方形偏析，對鋼材的質量的影響是顯著的，特別是切削加工量很大的零件或心部受力的模具零件。偏析除了影響模具鋼力學性能的等向性外，對模具的拋光性能也有一定的影響。因此，國外相關的標準中有嚴格的規(guī)定。

當今**鋼、超**鋼很好的實現(xiàn)了車輛的輕量化，提高了車輛的碰撞強度和安全性能，因此成為車用鋼材的重要發(fā)展方向。但隨著板料強度的提高，傳統(tǒng)的冷沖壓工藝在成型過程中容易產(chǎn)生破裂現(xiàn)象，無法滿足**度鋼板的加工工藝要求。在無法滿足成型條件的情況下，國際上逐漸研究超**度鋼板的熱沖壓成形技術。該技術是綜合了成形、傳熱以及組織相變的一種新工藝，主要是利用高溫奧氏體狀態(tài)下，板料的塑性增加，屈服強度降低的特點，通過模具進行成形的工藝。但是熱成型需要對工藝條件、金屬相變、CAE分析技術進行深入研究，該技術被國外廠商壟斷，國內發(fā)展緩慢。

中國鋼材及國內外黑色系列商品產(chǎn)能巨大，仍然對市場虎視眈眈。盡管因為前期市場價格跌破中位成本，鋼材及國黑色系列商品企業(yè)利潤急劇縮水，甚至出現(xiàn)虧損，致使產(chǎn)量下降，市場供求關系改善，但是這些龐大產(chǎn)能依然存在，并未真正退出市場。一旦價格回升至有利可圖，幾乎所有企業(yè)都會爭先恐后復產(chǎn)和增產(chǎn)，地方出于多方面考慮也會樂觀其成，這是什么力量也擋不住的。大量新增資源一擁而上，重現(xiàn)嚴重供大于求，價格勢必再次大跌。鋼材及黑色系列商品價格在超跌反彈后難以持續(xù)下去，難以出現(xiàn)長時間的的大幅度上漲。
