ASTM A285/A285M-12
(Specification)Standard Specification for Pressure Vessel Plates, Carbon Steel, Low- and Intermediate-Tensile Strength
Standard Specification for Pressure Vessel Plates, Carbon Steel, Low- and Intermediate-Tensile Strength
ABSTRACT
This specification covers carbon steel plates of low- and intermediate-tensile strengths which may be made by killed, semi-killed, capped, or rimmed steel. These plates are intended for fusion-welded pressure vessels. Plates are normally supplied in the as-rolled condition. 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 carbon steel plates of low- and intermediate-tensile strengths which may be made by killed, semi-killed, capped, or rimmed steel practices at the producer's option. These plates are intended for fusion-welded pressure vessels.
1.2 Plates under this specification are available in three grades having different strength levels as follows: Grade Tensile Strength, ksi [MPa] A 45–65 [310–450] B 50–70 [345–485] C 55–75 [380–515]
1.3 The maximum thickness of plates under this specification, for reasons of internal soundness, is limited to a maximum thickness of 2 in. [50 mm] for all grades.
Note 1—For killed carbon steels only refer to the following ASTM specifications:
A 299/A 299M Pressure Vessel Plates, Carbon Steel, Manganese-
Silicon.
A 515/A 515M Pressure Vessel Plates, Carbon Steel, for
Intermediate- and Higher-Temperature Service
A 516/A 516M Pressure Vessel Plates, Carbon Steel, for Moderate-
and Lower-Temperature Service.
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
