(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 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 as rolled. The product is furnished in two types and four strength grades as agreed upon between the producer and purchaser. These types and strength level grades are shown in the tables.
1.2 The maximum thickness of plates shall be as follows:Grade Plate Thickness, max in. [mm]502 [50]6011/2 [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 A6/A6M for information on weldability.
1.4 For plate produced from coil, the additional requirements, including additional testing requirements and the reporting of additional test results, of Specification A6/A6M apply.

1. Scope
1.1 This specification covers 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 shall
be made to a killed steel fine grain practice, and include specified alloying elements. These steels are normally furnished as rolled.
The product is furnished in two types and four strength grades as agreed upon between the producer and purchaser. These types
and strength level grades are shown in the tables.
