Grades42 290, 50 345, and 55 380 are intended for riveted, bolted, or welded structures. Grades 60 415 an

4、d 65 450 are intendedfor 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 areto be negotiated between the purchase

5、r and the producer.1.3 Specification A588/A588M shall not be substituted for Specification A572/A572M without agreement between thepurchaser and the supplier.1.4 The use of columbium, vanadium, titanium, nitrogen, or combinations thereof, within the limitations noted in Section 5, isrequired; the se

6、lection of type (1, 2, 3, or 5) is at the option of the producer, unless otherwise specified by the purchaser. (SeeSupplementary Requirement S90.)1.5 The maximum thicknesses available in the grades and products covered by this specification are shown in Table 1.1.6 When the steel is to be welded, a

7、welding procedure suitable for the grade of steel and intended use or service is to beutilized. 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

8、are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system is to be usedindependently of the other, without combining values in any way.1.8 The text of this specification contains notes or footnotes, or both, that provide explanatory material. Such note

9、s andfootnotes, excluding those in tables and figures, do not contain any mandatory requirements.1.9 For structural products produced from coil and furnished without heat treatment or with stress relieving only, the additionalrequirements, including additional testing requirements and the reporting

10、of additional tests, of A6/A6M apply.2.

General Requirements for Delivery3.1 Structural products furnished under this specification shall conform to the requirements of the current edition ofSpecification A6/A6M, for the specific structural product ordered, unless a conflict exists in which case this

17、specification shallprevail.3.2 Coils are excluded from qualification to this specification until they are processed into a finished structural product.Structural products produced from coil means structural products that have been cut to individual lengths from a coil. Theprocessor directly controls

18、, or is responsible for, the operations involved in the processing of a coil into a finished structuralproduct. Such operations include decoiling, leveling or straightening, hot-forming or cold-forming (if applicable), cutting to length,testing, inspection, conditioning, heat treatment (if applicabl

19、e), packaging, marking, loading for shipment, and certification.NOTE 1For structural products produced from coil and furnished without heat treatment or with stress relieving only, two test results are to be reportedfor each qualifying coil. Additional requirements regarding structural products prod

20、uced from coil are described in A6/A6M.4. Materials and Manufacture4.1 The steel shall be killed5. Chemical Composition5.1 The heat analysis shall conform to the requirements prescribed in Table 2 and Table 3.5.2 The steel shall conform on product analysis to the requirements prescribed in Table 2 a
