Introduction to the Steel Forging Standards for Pressure Vessels (一)——Carbon and Low-alloy Steel Forgings for Pressure Vessels

本文简要介绍了压力容器用碳素钢和低合金钢锻件标准。本标准的技术要求较原标准JB755-85有了很大提高。例如,对锻件的抗拉强度上限作出了规定,冲击试验采用夏比V型缺口试样,锻件的高温屈服强度作为附加要求等。

The paper briefly introduces the carbon and low-alloy steel forgings standard for pressure vessels. The technical requirements of the standard has made great improvement comparing with the previous standard JB755-85. For example, the standard stipulates the upper limit of tensile strength of the forgings, charpy V-notch specimen is applied to impact test and the yield strength at high temperature of the forgings is regarded as a supplementary requirement and so on.
