但9Mn2V鋼也存在一些缺點(diǎn)如沖擊韌性不高，在生產(chǎn)使用中發(fā)現(xiàn)有碎裂現(xiàn)象.另外回火穩(wěn)定性較差，回火溫度一般不超過18℃在2℃回火時(shí)抗彎強(qiáng)度及韌性開始出現(xiàn)低值。n2V鋼可在硝鹽、熱油等冷卻能力較為緩和的淬火介質(zhì)中淬火。對(duì)于一些變形要求嚴(yán)格而硬度要求又不很高的模具，可采用奧氏體等溫淬火。尺寸大、形狀復(fù)雜重負(fù)荷的冷作模具。須采用中合金或高合金鋼.如Cr12Mo、Crl2MoV、Cr6WV、Cr4W2MoV等，另外也有選用高速鋼的。

低磷鋼生產(chǎn)技術(shù)鋼中磷過高，在凝固時(shí)會(huì)產(chǎn)生嚴(yán)重的偏析而導(dǎo)致產(chǎn)品脆裂。對(duì)于高級(jí)管線鋼則需要將磷降至100ppm以下，而對(duì)于在極寒冷地區(qū)使用的管線鋼，為防止冷脆，甚至需要將鋼中的磷含量控制在50ppm以下。寶鋼相繼開展了如下的工藝試驗(yàn)：鐵水三脫+轉(zhuǎn)爐小渣量（渣量指數(shù)為0.3）冶煉工藝（方式A）鐵水脫硫+轉(zhuǎn)爐大渣量（渣量指數(shù)為1.0）冶煉工藝（方式B）鐵水三脫+轉(zhuǎn)爐大渣量（渣量指數(shù)為1.0）冶煉工藝（方式C）轉(zhuǎn)爐預(yù)處理脫磷+脫碳轉(zhuǎn)爐中渣量（渣量指數(shù)為0.6）冶煉工藝（方式D）上述4種不同脫磷工藝效果如下：采用三脫鐵水少渣量工藝的轉(zhuǎn)爐終點(diǎn)平均磷含量為120ppm；采用通常脫硫鐵水的大渣量工藝的轉(zhuǎn)爐終點(diǎn)平均磷含量為100ppm；采用三脫鐵水大渣量工藝的轉(zhuǎn)爐終點(diǎn)平均磷含量為66ppm；而采用轉(zhuǎn)爐脫磷預(yù)處理鐵水+脫碳爐中渣量工藝轉(zhuǎn)爐終點(diǎn)平均磷含量達(dá)到58ppm，由此可見，方式方式D均為生產(chǎn)超低磷鋼的有效工藝。
