Designation: A516/A516M −25 Used in USDOE-NE Standards
Standard Speciﬁcation for
Pressure Vessel Plates, Carbon Steel, for Moderate- and
Lower-Temperature Service
1
This standard is issued under the ﬁxed designation A516/A516M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number 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 U.S. Department of Defense.
1. Scope*
1.1 This speciﬁcation
2
covers carbon steel plates intended
primarily for service in welded pressure vessels where im-
proved notch toughness is important.
1.2 Plates under this speciﬁcation are available in four
grades having different strength levels as follows:
Grade U.S. [SI] Tensile Strength,
ksi [MPa]
55 [380] 55–75 [380–515]
60 [415] 60–80 [415–550]
65 [450] 65–85 [450–585]
70 [485] 70–90 [485–620]
1.3 The maximum thickness of plates is limited only by the
capacity of the composition to meet the speciﬁed mechanical
property requirements.
1.4 For plates produced from coil and furnished without
heat treatment or with stress relieving only, the additional
requirements, including additional testing requirements and the
reporting of additional test results of Speciﬁcation A20/A20M
apply.
1.5 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 speciﬁ-
cation.
1.6 This international standard was developed in accor-
dance with internationally recognized principles on standard-
ization established in the Decision on Principles for the
Development of International Standards, Guides and Recom-
mendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.

3. General Requirements and Ordering Information
3.1 Material supplied to this product speciﬁcation shall
conform to Speciﬁcation A20/A20M, which outlines the test-
ing and retesting methods and procedures, permissible varia-
tions in dimensions and mass, quality and repair of defects,
marking, loading, and ordering information.
3.2 In addition to the basic requirements of this
speciﬁcation, certain supplementary requirements are available
where additional control, testing, or examination is required to
meet end use requirements. The purchaser is referred to the
listed supplementary requirements in this speciﬁcation and to
the detailed requirements in Speciﬁcation A20/A20M.
3.3 If the requirements of this speciﬁcation are in conﬂict
with the requirements of Speciﬁcation A20/A20M, the require-
ments of this speciﬁcation shall prevail.
3.4 Coils are excluded from qualiﬁcation to this speciﬁca-
tion until they are processed into ﬁnished plates. Plates
produced from coil means plates that have been cut to
individual lengths from coil. The processor directly controls, or
is responsible for, the operations involved in the processing of
coils into ﬁnished plates. Such operations include decoiling,
leveling, cutting to length, testing, inspection, conditioning,
heat treatment (if applicable), packaging, marking, loading for
shipment, and certiﬁcation.

normalized.

5.3 When notch-toughness tests are required on plates

⁄

in. [40 mm] and under in thickness, the plates shall be

normalized unless otherwise speciﬁed by the purchaser.

5.4 If approved by the purchaser, cooling rates faster than

those obtained by cooling in air are permissible for improve-

ment of the toughness, provided the plates are subsequently

tempered in the temperature range 1100 °F to 1300 °F [595 °C

to 705 °C].

6. Chemical Composition

6.1 The steel shall conform to the chemical requirements

given in Table 1 unless otherwise modiﬁed in accordance with
