介绍了马氏体钢４Ｃｒ１０Ｓｉ２Ｍｏ气阀的锻造工艺及生产中的注意事项，分析了这种钢不能采用空冷的原因，并且与奥氏体钢４Ｃｒ１４Ｎｉ１４Ｗ２Ｍｏ气阀的锻造特点进行了比较，提出了气阀生产新工艺———正挤压的可行性．
The forging process of the martensitic steel 4Cr10Si2Mo valve and the precautions in the production are introduced. The reason why the steel can not be air-cooled is analyzed, and the forging characteristics of the austenitic steel 4Cr14Ni14W2Mo valve are compared. The gas valve Production of new technology --- is the feasibility of extrusion.
