ASTM A572 standard is for high strength low alloy (HSLA) structural steel plate integrated with columbium-vanadium, the specification covers 5 grades of HSLA steel profiles, plates, sheet piling, and bars.
Applications of A572 Steel Plates:
Grades 42, 50, 55 are intended for riveted, bolted or welded structurals, Grade 60 and 65 are for riveted and bolted construction of bridges, welded constructions and more applications.

A: Specimen shall comply with Specification of A6/A6M.
B: Elongation not required to be determi ed for floor plate.
C: For wide flange shapesover 426 lb/ft [634 kg/m], elongation in 2 in. [50 mm] of 19% minimum applies.
D: For plates wider than 24 in. [600 mm], the elongation requirement is reduced two percedntage points for Grade 42, 50, and 55 [290,345,and 380], and three percentage points for Grade 60 and 65 [415 and 450]. See elongation requirement asjustments in the Tesion Tests section of Specification A6/A6M.
General Requirements for Delivery
Structural steel plates furnished underASTM A572 shall comply with requirements of the current edition of Specification A6/A6M, for the specific structural product ordered, unless a conflict exists in which case this specification shall prevail.
Coils are not applicable to this specification until they are processed to a finished structural product. Structural steel plates produced from coil means they 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 a finished structural product. Such operations include decoiling, leveling or straightening, hot-forming or cold-forming (if applicable), cutting to length, testing, inspection, conditioning, heat treatment (if applicable), packing, marking, loading for shipment, and certification.
