Materials of Construction

Abstract

The requirements for materials are covered in Chapter III of ASME B31.3. Selection of the appropriate material for a given service is not covered by the Code. As stated in para. 323.5, “Selection of materials to resist deterioration in service is not within the scope of this Code.” Practical considerations make it impossible for the Code to provide guidance relevant to the essentially unlimited process applications covered by the Code. Some precautionary considerations are included in Appendix F based on specific experience or interests of Code Committee members, but this is a very limited list of considerations.
