ASTM A455/A455M-12a
(Specification)Standard Specification for Pressure Vessel Plates, Carbon Steel, High-Strength Manganese
Standard Specification for Pressure Vessel Plates, Carbon Steel, High-Strength Manganese
ABSTRACT
This specification covers high-tensile strength carbon-manganese steel plates intended for welded pressure vessels. Plates are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both. The steel shall conform to the chemical composition requirements. The plates, as represented by the tension test specimens, shall conform to the mechanical property requirements.
SCOPE
1.1 This specification2 covers high-tensile strength carbon-manganese steel plates intended for welded pressure vessels.
1.2 This steel is usually made to a semi-killed or capped deoxidation practice; however, at the purchaser's or the steel producer's option, the steel may be made silicon-killed or aluminum-killed.
1.3 The maximum thickness of plates furnished under this specification shall be 3/4 in. [20 mm].
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 specification.

This document is not an ASTM standard and is intended only to provide the user of an ASTM 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.

3. General Requirements and Ordering Information
3.1 Material supplied to this material specification shall conform to Specification A20/A20M. These requirements outline the
testing and retesting methods and procedures, permitted variations 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 when 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 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.
3.4 If the requirements of this specification are in conflict with the requirements of Specification A20/A20M, the requirements
of this specification shall prevail.
