Control of Ferrite Content in Stainless Steel Weld Metal

The U.S. Nuclear Regulatory Commission (NRC or the Commission) is issuing for public comment draft regulatory guide (DG), DG-1279, "Control of Ferrite Content in Stainless Steel Weld Metal." This guide describes a method that the NRC staff considers acceptable for controlling ferrite content in stainless steel weld metal. Revision 4 updates the guide to remove references to outdated standards and to remove an appendix that has been incorporated into relevant specifications.
