SFA-5.23/SFA-5.23M ASME BPVC.II.C-2023

Specification for Low-Alloy and High Manganese Steel
Electrodes and Fluxes for Submerged Arc Welding
1. Scope
1.1 This specification prescribes requirements for the classification of solid and composite carbon steel, low-alloy steel,
and high manganese steel electrodes and flux-electrode combinations for submerged arc welding SAW. This specification
covers low-alloy and high manganese electrodes and low-alloy and high manganese multiple-pass flux-electrode
classifications. This specification also addresses carbon steel, low-alloy steel, and high manganese steel two-run fluxelectrode
classifications. The multiple-pass classification of flux-electrode combinations for carbon steel SAW is not
within the scope of this specification, but is covered in AWS A5.17/A5.17M.
1.2 This specification makes use of both U.S. Customary Units and the International System of Units SI. The measurements
are not exact equivalents; therefore, each system must be used independently of the other without combining in any way
when referring to weld metal properties. The specification with the designation A5.23 uses U.S. Customary Units. The
specification A5.23M uses SI Units. The latter are shown within brackets [ ], in appropriate columns in tables and figures
and in paragraphs numbered with an “M” suffix. Standard dimensions based on either system may be used for the sizing
of electrodes, packaging, or both under specification A5.23 or A5.23M.
1.3 Safety and health issues and concerns are beyond the scope of this standard; some safety and health information is
provided, but such issues are not fully addressed herein. Some safety and health information can be found in Annex A
Clauses A5 and A11. Safety and health information is available from the following sources:
American Welding Society:
1 ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes
2 AWS Safety and Health Fact Sheets
3 Other safety and health information on the AWS website
Material or Equipment Manufacturers:
1Safety Data Sheets supplied by materials manufacturers
2 Operating Manuals supplied by equipment manufacturers
Applicable Regulatory Agencies
Work performed in accordance with this standard may involve the use of materials that have been deemed hazardous and
may involve operations or equipment that may cause injury or death. This standard does not purport to address all safety
and health risks that may be encountered. The user of this standard should establish an appropriate safety program to
address such risks as well as to meet applicable regulatory requirements. ANSI Z49.1 should be considered when developing
the safety program.
2. Normative References
The documents listed below are referenced within this publication and are mandatory to the extent specified herein. For
undated references, the latest edition of the referenced standard shall apply. For dated references, subsequent amendments
to or revisions of any of these publications do not apply.
