The flange material is ASTM A737 Gr.C , and to use ASME B16.5 to specify the flange class, I do not know what material table corresponds to this material. Can somebody shed light, please.
The flange material in the Datasheet of my project is P460 according to ASTM is A737Gr c . I find this material in the ASME Div II part D but I don’t find in the asme B16.5 . how I can determine the class and dimensions of my wild neck flange with this material ?
