It would be extremely useful to add additional carbon steel flange material to the database drop down list. In my experience, the majority of the pipelines are comprised of the materials shown below and their flanged equivalent. Please add the following list of materials to the database. This would make the flange analysis evaluation much more seamless for nearly all of my piping applications.
