Standard Specification for
Pressure Vessel Plates, Carbon Steel, High-Strength
Manganese
This standard is issued under the fixed designationA 455/A 455M; 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 covers high-tensile strength carbon-manganese steel plates intended for welded pressure vessels.
1.2 This materialsteel is usually made to a semi-killed or capped deoxidation practice. However,practice; however, at the
purchaser’s or the steel producer’s option, the materialsteel may be made silicon-killed or aluminum-killed.
1.3 The maximum thickness of plates furnished under this specification shall be ⁄4 in. [20 mm].
1.4For plates produced from coil, the additional requirements, including additional testing requirements and the reporting of
additional test results, of Specification A20/A20M
1.4 Forplatesproducedfromcoilandfurnishedwithoutheattreatmentorwithstressrelievingonly,theadditionalrequirements,
including additional testing requirements and the reporting of additional test results, of Specification A 20/A 20M 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 specification.

3. General Requirements and Ordering Information
3.1Material supplied to this material specification shall conform to Specification A20/A20M. These requirements outline the
testing and retesting methods and procedures, permissible variations in dimensions, and mass, quality and repair of defects,
marking, loading, etc.
3.2Specification A20/A20M also establishes the rules for the ordering information that should be complied with when
purchasing material to this specification.
3.3In addition to the basic requirements, two supplementary requirements are available to meet end use requirements as follows:
3.3.1Simulated post-weld heat treatment of test coupons, and
3.3.2Bend test.
3.4The purchaser is referred to the listed supplementary requirements in this specification and to the detailed requirements in
Specification A20/A20M.
3.5Coiled product is excluded from qualification to this specification until it is decoiled, leveled, and cut to length. Plate
produced from coil means plate that has been cut to individual lengths from a coiled product and is furnished without heat
treatment. The processor decoils, levels, cuts to length, and marks the product. Except as allowed by Section 6 in Specification
A20/A20M, the processor is responsible for performing and certifying all tests, examinations, repairs, inspections, and operations
not intended to affect the properties of the material. For plate produced from coils, the results of the tests performed shall be
reported for each qualifying coil. See Note 1 General Requirements and Ordering Information
3.1 Plates supplied to this product specification shall conform to Specification A 20/A 20M, which outlines the testing and
retesting methods and procedures, permissible variations in dimensions and mass, quality and repair of defects, marking, loading,
etc.
This specification is under the jurisdiction of ASTM Committee A01 on Steel, Stainless Steel,Steel and Related Alloys and is the direct responsibility of Subcommittee
A01.11 on Steel Plates for Boilers and Pressure Vessels.

3. General Requirements and Ordering Information
3.1 Plates supplied to this product specification shall conform to Specification A 20A20/A20M/A 20M,, which outlines the
testing and retesting methods and procedures, permissible variations in dimensions and mass, quality and repair of defects,
marking, loading, etc.
3.2 SpecificationA20A20/A20M/A20M also establishes the rules for ordering information that should be complied with when

3.4 The purchaser is referred to the listed supplementary requirements in this specification and to the detailed requirements in
Specification A 20A20/A20M/A 20M. .
3.5 Coils are excluded from qualification to this specification 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.
NOTE 1—For plates produced from coil and furnished without heat treatment or with stress relieving only, three test results are reported for each
qualifying coil. Additional requirements regarding plates from coil are described in Specification A20/A20M.
3.6 If the requirements of this specification are in conflict with the requirements of Specification A 20A20/A20M/A 20M,, the
requirements of this specification shall prevail.
4. Heat Treatment
4.1 Plates are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both.
This specification is under the jurisdiction of ASTM Committee A01 on Steel, Stainless Steel,Steel and Related Alloys and is the direct responsibility of Subcommittee
A01.11 on Steel Plates for Boilers and Pressure Vessels.
