Designation: A 553/A 553M – 06
Standard Specification for
Pressure Vessel Plates, Alloy Steel, Quenched and
Tempered 8 and 9 % Nickel
1
This standard is issued under the fixed designation A 553/A 553M; 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 (e) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This specification
2
covers 8 and 9 % nickel alloy steel
plates for use in the water quenched and tempered condition
intended for the fabrication of welded pressure vessels.
1.2 Material under this specification is available in two
types having different chemical composition as follows:
Type
Nominal Nickel
Content, %
I
II
9
8
1.3 Plates produced under this specification are subject to
impact testing at −320°F [−195°C] for Type I, and −275°F
[−170°C] for Type II or at such other temperatures as are
agreed upon.
1.4 The maximum thickness of plates is limited only by the
capacity of the material to meet the specified mechanical
property requirements; however, current mill practice normally
limits this material to 2 in. [50 mm] max.
1.5 This material is susceptible to magnetization. Use of
magnets in handling after heat treatment should be avoided if
residual magnetism would be detrimental to subsequent fabri-
cation or service.
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 specifi-
cation.

3. General Requirements and Ordering Information
3.1 Material supplied to this material specification shall
conform to Specification
A 20/A 20M. These requirements
outline the testing and retesting methods and procedures,
permissible variations in dimensions, and mass, quality and
repair of defects, marking, loading, etc.
3.2 Specification
A 20/A 20M also establishes the rules for
the ordering information which should be complied with when
purchasing material to this specification.
3.3 In addition to the basic requirements of this specifica-
tion, certain supplementary requirements are available when
additional control, testing, or examination is required to meet
end use requirements. These include:
3.3.1 Vacuum treatment,
3.3.2 Additional or special tension testing,
3.3.3 Impact testing, and
3.3.4 Nondestructive examination.
3.4 The purchaser is referred to the listed supplementary
requirements in this specification and to the detailed require-
ments in Specification
A 20/A 20M.
3.5 If the requirements of this specification are in conflict
with the requirements of Specification
A 20/A 20M, the re-
quirements of this specification shall prevail.
4. Manufacture
4.1 Steelmaking Practice—The steel shall be killed and
shall conform to the fine austenitic grain size requirement of
Specification
A 20/A 20M.
