ASTM B725-22

Die Annotation des Normtextes ASTM B725-22 :

This specification covers UNS N02200 nickel alloy and UNS N02201 and N04400 low carbon nickel alloy welded pipes intended for general corrosive service and for mechanical applications. Each pipe should either be welded and annealed or welded and stress relieved and made from the flat-rolled alloys by an automatic welding process without any filler metal additions. The pipes should also be cold worked after welding to ensure the development of optimum corrosion resistance in the weld area and base metal during the final heat treatment.
