Carbon Structural Steel1

Designation: A 36/A 36M – 00a

Standard Specification for

Carbon Structural Steel1

This standard is issued under the fixed designation A 36/A 36M; 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.

This standard has been approved for use by agencies of the Department of Defense.

1. Scope

1.1 This specification2 covers carbon steel shapes, plates,

and bars of structural quality for use in riveted, bolted, or

welded construction of bridges and buildings, and for general

structural purposes.

1.2 Supplementary requirements are provided for use where

additional testing or additional restrictions are required by the

purchaser. Such requirements apply only when specified in the

purchase order.

1.3 When the steel is to be welded, a welding procedure

suitable for the grade of steel and intended use or service is to

be utilized. See Appendix X3 of Specification A 6/A 6M for

information on weldability.

1.4 For Group 4 and 5 wide flange shapes for use in tension,

it is recommended that the purchaser consider specifying

supplementary requirements, such as fine austenitic grain size

and Charpy V-notch impact testing.

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 is to

be used independently of the other, without combining values

in any way.

1.6 The text of this specification contains notes or footnotes,

or both, that provide explanatory material. Such notes and

footnotes, excluding those in tables and figures, do not contain

any mandatory requirements.

1.7 For plates cut from coiled product, the additional

requirements, including additional testing requirements and the

reporting of additional test results, of A 6/A 6M apply.

without heat treatment. The processor decoils, levels, cuts to

length, and marks the product. The processor is responsible for

performing and certifying all tests, examinations, repairs,

inspections or operations not intended to affect the properties

of the material. For plates produced from coils, two test results

shall be reported for each qualifying coil. See Note 1.

NOTE 1—Additional requirements regarding plate from coil are described

in Specification A 6/A 6M.

5. Bearing Plates

5.1 Unless otherwise specified, plates used as bearing plates

for bridges shall be subjected to mechanical tests and shall

conform to the tensile requirements of Section 8.

5.2 Unless otherwise specified, mechanical tests shall not be

required for plates over 11⁄2 in. [40 mm] in thickness used as

bearing plates in structures other than bridges, subject to the

requirement that they shall contain 0.20 to 0.33 % carbon by

heat analysis, that the chemical composition shall conform to

the requirements of Table 2 in phosphorus and sulfur content,
