(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 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.
