1. Scope
1.1 This specification covers wrought-carbon steel butt-welding seamless or welded fittings specially processed to ensure better notch toughness than that to be expected in fittings manufactured to the requirements of Specification A234/A234M.
1.1.1 Included are elbows, caps, tees, reducers, and other type fittings covered by ASME B 16.9.
1.1.2 Heat treatment is required for all fittings.
1.1.3 Fittings with mandatory radiographic examination of welds are included.
1.1.4 Supplementary requirements are provided for use when additional testing or examination is desired.
1.1.5 Cast fittings, and fittings formed from all weld metal, are not included.
