The Material selection of ASME at different temperatures

In our daily work,a lot of clients asking for application of cryogenic valve,here we prepared some useful suggestion about the different material of cryogenic valves;

1.ZhengFeng valves consider that the Charpy impact energy table for materials of different thicknesses can have certain reference value for the basic properties and basic temperatures of the materials.

2.The material combination table according to different temperatures (degrees Fahrenheit) is as follows:

3.Zhengfeng's selection of bolt & nuts materials at different temperatures is as follows according to ASME table 11-9:
