(Specification)Standard Specification for Pressure Vessel Plates, Carbon Steel, High Strength, for Moderate and Lower Temperature Service
Standard Specification for Pressure Vessel Plates, Carbon Steel, High Strength, for Moderate and Lower Temperature Service
ABSTRACT
This specification covers killed carbon- manganese-silicon steel plates intended for welded pressure vessels in service at moderate and lower temperatures. As a steel making practice, the steel shall be killed and shall conform to specified fine austenitic grain size requirements. Plates are normally supplied in the as-rolled condition. Plates may be ordered normalized or stress relieved, or both. The steel shall conform to the required chemical compositions. The plates, as represented by the tension test specimens, shall conform to the mechanical property requirements.
SCOPE
1.1 This specification covers killed carbon-manganese-silicon steel plates intended for welded pressure vessels in service at moderate and lower temperatures.
1.2 The maximum thickness of plates supplied under this specification is 1 in. [25 mm].
1.3 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.
1.4 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.
