(Specification)Standard Specification for Hot-Rolled Structural Steel, High-Strength Low-Alloy Plate with Improved Formability
Standard Specification for Hot-Rolled Structural Steel, High-Strength Low-Alloy Plate with Improved Formability
ABSTRACT
This specification covers the three types and four strength grades of high strength low-alloy, hot rolled structural steel plate with improved formability. These steels are normally furnished in the as-rolled condition. For plates produced from coil, and furnished without heat treatment or with stress relieving only, additional testing requirements and the reporting of additional test results, of a reference material shall apply. Chemical composition requirements shall be dependent upon thickness, grade, and intended applications. Tension tests shall be executed to evaluate conformance of specimens with specified mechanical properties requirements.
SCOPE
1.1 This specification covers three types and five strength grades of high-strength low-alloy, hot-rolled structural steel plate for use in truck frames, brackets, crane booms, rail cars, and similar applications. Steels that conform to this specification offer improved formability. These steels are normally furnished in the as-rolled condition. The type and strength grade furnished is as agreed upon between the manufacturer and the purchaser. The types and strength grades are shown in the tables.
1.2 The maximum thickness of plates shall be as follows:
Grade
Plate Thickness, max,
in. [mm]
50
2 [50]
60
11/2 [40]
70
1 [25]
80
1 [25]
100
1/2 [13]
1.3 The values stated in either inch-pound units or SI units are to be regarded 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 this specification.
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 A6/A6M apply.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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 for Delivery
3.1 Plates furnished under this specification shall conform to the requirements of the current edition of Specification A6/A6M, for
the specific plate ordered, unless a conflict exists, in which case this specification shall prevail.
3.2 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 a coil. The processor directly controls, or is responsible for, the
operations involved in the processing of a coil 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, two test results are to be reported for each
qualifying coil. Additional requirements regarding plate produced from coil are described in Specification A6/A6M.
