    ASTM A663 / A663M

    1. Scope

    1.1 This specification covers hot-wrought merchant quality carbon steel bars and bar size shapes produced to mechanical property requirements and intended for noncritical constructional applications (see ).

    1.2 Merchant quality hot-wrought steel bar is available in the following ranges of size and section:

    1.2.1 Rounds, squares, and hexagons with diameters or distance across flats under 3 in. [75 mm].

    1.2.2 Bar size shapes with maximum dimensions under 3 in. [75 mm].

    1.2.3 Other bar sections with weight per foot under 40.84 lb/ft [60.78 kg/m].

    1.2.4 Flats 6 in. [152 mm] or under in width, over 0.203 in. [over 5 mm in thickness up to 150 mm in width] in thickness, and under 40.84 lb/ft or 12 in.2[77.4 cm2] in cross-sectional area.

    1.2.5 Flats over 6 in. to 8 in., inclusive in width, 0.230 in. and over [over 6 mm in thickness and over 50 mm through 200 mm in width] in thickness and under 40.84 lb/ft [60.78 kg/m] or 12 in.2 [77.4 cm2] in cross-sectional area.

    1.2.6 Hot-wrought merchant quality carbon steel bars subject to mechanical property requirements are hot wrought in straight lengths only.

    1.3 Some applications may require one or more of the available designations shown under supplementary requirements. Note 1Special quality hot-wrought carbon steel bars subject to mechanical property requirements are covered in Specification A 675/A 675M.
