(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
SCOPE
1.1 This specification covers two types and four 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, maxin. [mm]502 [50]601 1/2[40]701 [25]803/4[20]
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. See Appendix X3 of Specification A 6/A 6M for information on weldability.
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 A 6/A 6M apply.

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

3.1.1Coiled product is excluded from qualification to this specification until it is decoiled, leveled and cut to length. Plate
produced from coil means plate that have been cut to individual lengths from a coiled product and are furnished 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 plate
produced from coils, two test results shall be reported for each qualifying coil. General Requirements for Delivery
3.1 Plates furnished under this specification shall conform to the requirements of the current edition of SpecificationA 6/A 6M,
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
