The result of industrial experiment had shown that jaw made of this material last equally with that of high Cr Mo cast iron, and this material is low_cost.

试验结果表明，使用该材料制作的牙板其使用寿命与高铬钼铸铁牙板相当，且生产成本低。

The Zinc and Aluminum anode protector can prevent the Cr-Mo steel from corrosion. However, it has the obvious effect of accelerating the crack propagation.

采用锌阳极和铝阳极的防止腐蚀方法虽能防止铬钼钢腐蚀，但对其裂纹的扩展起明显的加速作用。

The effect of postwelding heat treatment on property of pressure equipment made of Cr-Mo steel has been interpreted thorough some research and practical examples.

前言： 通过一些试验研究和工程实例，介绍采用铬钼钢制造的承压设备，经热处理后对钢材性能的影响。
