1.1 This specification covers five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars. Grades 42 [290], 50 [345], and 55 [380] are intended for riveted, bolted, or welded structures. Grades 60 [415] and 65 [450] are intended for riveted or bolted construction of bridges, or for riveted, bolted, or welded construction in other applications. 1.2 For applications, such as welded bridge construction, where notch toughness is important, notch toughness requirements are to be negotiated between the purchaser and the producer. 1.3 Specification A588/A588M shall not be substituted for Specification A572/A572M without agreement between the purchaser and the supplier. 1.4 The use of columbium, vanadium, titanium, nitrogen, or combinations thereof, within the limitations noted in Section 1.5 The maximum thicknesses available in the grades and products covered by this specification are shown in Grade |

1.6 When the steel is to be welded,
a welding procedure suitable for the grade of steel and intended
use or service is to be utilized. See Appendix X3 of Specification
A6/A6M for information on weldability.

1.7 The values stated in either
inch-pound units or SI units are to be regarded separately 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 is to be used independently of the other, without
combining values in any way.
