1- Flange material shall be selected based on service conditions (fluid
properties such as corrosiveness, temperature, hydrogen contents,...).
2- Based on design pressure, design temperature and material of
construction the flange rating shall be selected according to
pressure/temperature rating tables of ASME b16.5.
Based on my long experience on this matter I found that working with
pressure/temperature rating tables of ASME b16.5 is not so easy and
accurate. So I converted these tables to the graphs which is in
attached as a pdf file for your convenience.

Hope it will be useful for you.

Regards,
Karandish
