通常錘鍛模工作時．其模腔表面溫度可達300～400℃以上熱擠壓模可達500一800℃以上；壓鑄模模腔溫度與壓鑄材料種類及澆注溫度有關。如壓鑄黑色金屬時模腔溫度可達1000℃以上。這樣高的使用溫度會使模腔表面硬度和強度明顯降低，在使用中易發(fā)生打垛。為此．對熱作模具鋼的基本使用性能要求是熱塑變抗力高，包括高溫硬度和高溫強度、高的熱塑變抗力，實際上反映了鋼的高回火穩(wěn)定性。由此便可以找到熱模具鋼合金化的第一種途徑，即加入Cr、W、Si．等合金元素可以提高鋼的回火穩(wěn)定性。

1、氧含量。對模具鋼一般都未規(guī)定鋼中的允許的氣體含量。隨著氧含量的增加，氧化物的顆粒和數(shù)量都隨之增加，鋼的疲勞性能降低，熱裂紋也容易產生。有人曾對4Cr5MoSiV1鋼進行過試驗，近年來，為了提高模具的制造質量。國內外的模具鋼逐漸在向低氧含量的方向發(fā)展。2、疏松。疏松是鋼的不致密性的表現(xiàn)。疏松多數(shù)出現(xiàn)在鋼錠的上部及中部，在這些地方因為集中了較多的雜質和氣體造成的。由于疏松缺陷的存在，降低了鋼的強度和韌性，也嚴重地影響了加工后的表面的粗糙度，在一般的模具鋼中的影響不是特別大，但如冷軋輥、大型的模塊、沖頭和塑料成形模具零件等都有較嚴格的要求。如深型腔的鍛模和沖頭要求疏松不超過1級或2級，用于表盤或透光件等的塑料模具用鋼，要求疏松不超過1級。

中國鋼材及國內外黑色系列商品產能巨大，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，致使產量下降，市場供求關系改善，但是這些龐大產能依然存在，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)都會爭先恐后復產和增產，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。
