ASME SA-727-SA-727M-2021 pdf free download.SPECIFICATION FOR CARBON STEEL FORGINGS FOR PIPING COMPONENTS WITH INHERENT NOTCH TOUGHNESS.
1.1 This specification covers forged carbon steel piping components intended primarily for service in pressure piping systems from —20 to +650 F (—30 to +345 UCI where inherent notch toughness is desired, but where notch toughness testing is not required. Included are forged or ringrolled flanges. forged fittings, and valves made to specifIed dimensions, orb 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. 151 mml.
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.

1.5 This specification is expressed in both inch-pound units and in SI units. However, unless the order spceities the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units.
1.6 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

Information
3.1 Product furnished to this specilication shall conform to the requirements of Specification A 961/A 96lM.
including any supplemeniary requirements that are mdicated in the purchase order. Failure to compiy with the requirements of Specification A 961/A 961M constitutes nonconformance with this specification. In case of a conIlict between thc requirements of this specification and Specification A 961/A 961 M. (his specification shall prevail.
3.2 Ii is the purchaser’s responsibility to specify in the purchase order all ordering information necessary to purchase the needed material. Esamplcs of such information include but are not limited to the following;
3.2.1 Additional requirements (see l.l and l.2).
4. Materials and Manufacture
4.1 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.
4.2 lorgings shall be manufactured from ingots. blooms, billets, slabs, or bars. These items shall be forged. rolled, or strandcasi.
4.3 A sufticicnt discard shall be made from the ingot to secure freedom from injurious piping and undue segregation.
4.4 The finished product shall he a forging as defined by the Terminology section of Specification A 788/A 7X8M.ASME SA-727 pdf download.
