ASTM A182/A182M-11a

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Service
This standard is issued under the fixed designationA182/A182M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision.Anumber in parentheses indicates the year of last reapproval.
A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1. Scope*

1.1 This specification covers forged low alloy and stainless steel piping components for use in pressure systems. Included are
flanges, fittings, valves, and similar parts to specified dimensions or to dimensional standards, such as the ASME specifications
that are referenced in Section 2.
1.2 For bars and products machined directly from bar (other than those directly addressed by this specification; see 6.4), refer
toSpecificationsA479/A479MandA739forthesimilargradesavailableinthosespecifications.Productsmadetothisspecification
are limited to a maximum weight of 10000 lb [4540 kg]. For larger products and products for other applications, refer to
Specifications A336/A336M and A965/A965M for the similar ferritic and austenitic grades, respectively, available in those
specifications.
1.3 Several grades of low alloy steels and ferritic, martensitic, austenitic, and ferritic-austenitic stainless steels are included in
thisspecification.Selectionwilldependupondesignandservicerequirements.Severaloftheferritic/austenitic(duplex)gradesare
also found in Specification A1049/A1049M.
1.4 Supplementary requirements are provided for use when additional testing or inspection is desired. These shall apply only
when specified individually 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 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 the standard. Within the text, the
SIunitsareshowninbrackets.Thevaluesstatedineachsystemmaynotbeexactequivalents;therefore,eachsystemshallbeused
independently of the other. Combining values from the two systems may result in non-conformance with the standard.
