ASTM A285/A285M
Standard Specification for Pressure Vessel Plates, Carbon Steel, Low- and Intermediate-Tensile Strength
This specification2 covers four grades (A, B, C) of carbon steel plates of structural quality for general application.
1. Scope
1.1 This specification2 covers carbon steel plates of lowand
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:3
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 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.
2. General Requirements and Ordering Information
2.1 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.
2.2 Specification A 20/A 20M also establishes the rules for
the ordering information that should be complied with when
purchasing material to this specification.
2.3 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 A 20/A 20M.
2.4 If the requirements of this specification are in conflict
with the requirements of Specification A 20/A 20M, the requirements
of this specification shall prevail.
3. Heat Treatment
3.1 Plates are normally supplied in the as-rolled condition.
The plates may be ordered normalized or stress relieved, or
both.
4. Chemical Requirements
4.1 The steel shall conform to the requirements as to
chemical composition as shown in Table 1.
5. Mechanical Requirements
5.1 Tension Tests:
5.1.1 Requirements—The material as represented by the tension-test specimens shall conform to the requirements shown in Table 2.
Chemical Composition :
The heat analysis shall conform to the requirements prescribed in the Table.
The steel shall conform on product analysis to the requirements prescribed in Table, subject to the product analysis tolerances in Specification A6/A6M

Supplementary Requirements
Supplementary requirements shall not apply unless specified in the order.
A list of standardized supplementary requirements for use at the option of the purchaser are included
in Specification A 20/A 20M. Those which are considered suitable for use with this specification are
listed below by title.
S3. Simulated Post-Weld Heat Treatment of Mechanical Test Coupons
S3.1 Prior to testing, the test coupons representing the plate
for acceptance purposes for mechanical properties shall be
thermally treated to simulate a post-weld heat treatment below
the critical temperature (Ac3), using the heat treatment parameters
(such as temperature range, time, and cooling rates)
specified in the purchase order. For tests using specimens taken
from such heat treated test coupons, the test results shall meet
the requirements of the applicable product specification.
S4. Additional Tension Test
S4.1 Other Than Quenched-and-Tempered Plates—In addition
to the required single tension test, a second tension test
shall be made using a test specimen taken from a test coupon
taken from a corner of the plate-as-rolled on the end opposite
the single test specimen and in a direction parallel to the single
test specimen. The results obtained using this second test
specimen shall meet the requirements of the applicable product
specification.
S4.2 Quenched-and-Tempered Plates 2 in. [50 mm] or
Greater in Thickness—In addition to the required tension tests,
two additional test coupons shall be taken from the bottom
corner of the plate. One shall be taken at the center of the plate
thickness and the other immediately beneath the surface.
Mandatory conformance of these additional tests with the
specified properties shall be a matter of agreement between the
manufacturer and the purchaser.
S14. Bend Test.
Additional Suplementary Requirements
Also listed below are additional optional supplementary requirements suitable for this specification:
S57. Copper-Bearing
S57.1 The copper content, by heat analysis shall be
0.20–0.35 % and by product analysis 0.18–0.37 %.
S58. Restricted Copper
S58.1 The maximum incidental copper content by heat
analysis shall not exceed 0.25 %.
