(Specification)Standard Specification for Carbon Steel Forgings for Piping Components with Inherent Notch Toughness
Standard Specification for Carbon Steel Forgings for Piping Components with Inherent Notch Toughness
ABSTRACT
This specification covers forged carbon steel piping components intended primarily for service in pressure piping systems from a specific temperature range where inherent notch toughness is desired, but where notch toughness testing is not required. Included are forged or ring-rolled flanges, forged fittings, and valves made to specified dimensions. The steel shall be made by one or more of the following processes: open-hearth, basic-oxygen, or electric-furnace, and shall be fully killed, fine-grain practice. Following plastic working, the forgings shall be heat treated by normalizing, or normalizing and tempering, or quenching and tempering. The forgings shall be subjected to tension, hardness, and hydrostatic tests.
SCOPE
1.1 This specification2 covers forged carbon steel piping components intended primarily for service in pressure piping systems from −20 to +650 °F [−30 to +345 °C] where inherent notch toughness is desired, but where notch toughness testing is not required. Included are forged or ring-rolled flanges, forged fittings, and valves made to specified dimensions, or to dimensional standards such as the ASME and API specifications referenced in Section 2.
1.2 This specification is limited to forgings with maximum finished section thicknesses no larger than 2 in. [51 mm].
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 Supplementary requirements are provided for use when additional testing or inspection is desired. These shall apply only when specified by the purchaser in the order.
Note 1: There are no provisions for impact testing in this specification. When impact testing is required, refer to Specification A350/A350M.
1.5 This specification is expressed in both inch-pound units and in SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units.
1.6 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.
