Description

ASTM A758/A758M-24

Redline Standard: Standard Specification for Wrought-Carbon Steel Butt-Welding Piping Fittings with Improved Notch Toughness

ASTM A758/A758M

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 B16.9.

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.

1.2 Several type of fittings are provided, as follows:

1.3 It shall be the responsibility of the purchaser to determine whether material meeting the requirements of this specification is satisfactory for the service application.

1.4 This specification is expressed in both inch-pound units and SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units.

1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
