GSO ASTM A182/A182M:2014 Scope
1.1 This specification2 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 to Specifications A479/A479M and A739 for the similar
grades available in those specifications. Products made to this
specification are limited to a maximum weight of 10 000 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 this specification. Selection will depend upon design
and service requirements. Several of the ferritic/austenitic
(duplex) grades are 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 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.
