Overview of A709 steel plate       ASTM_A709_A709M-09.pdf


This specification covers carbon and high strength low alloy steel structural shapes, plates, and bars and quenched and tempered alloy steel for structural plates intended for use in bridges. Seven grades are available in four yield strength levels as follows:

is also included in Specifications A 36/A 36M,A 572/A 572M, A 992/A 992M, and A 588/A 588M, respectively.When the supplementary requirements of this specificationare specified, they exceed the requirements of Specifications A 36/A 36M, A 572/A 572M, A 992/A 992M, andA 588/A 588M.
1.1.2 Grades 50W [345W], HPS 50W [HPS 345W], HPS70W [HPS 485W], and HPS 100W [HPS 690W] have enhancedat mospheric corrosion resistance (see 13.1.2). Product availability is shown in Table 1.
1.2 Grade HPS 70W [HPS 485W] or HPS 100W [HPS 690W] shall not be substituted for Grades 36 [250], 50 [345],50S [345S], 50W [345W], or HPS 50W [HPS 345W]. Grade50W [345W], or HPS 50W [HPS 345W] shall not be substituted for Grades 36 [250], 50 [345] or 50S [345S] without agreement between the purchaser and the
steel supplier.
1.3 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A 6/A 6M for information on weldability.

1.4 For structural products to be used as tension components requiring notch toughness testing, standardized requirements are provided in this standard, and they are based upon American Association of State Highway and Transportation Officials (AASHTO) requirements for both fracture critical and non-fracture critical members.
1.5 Supplementary requirements are available but shallapply only if specified in the purchase order.
1.6 The values stated in either SI units or inchpound units are to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining alues from the two systems may result in non-conformance with the standard.
1.7 For structural products produced from coil and furnished without heat treatment or with stress relieving only, the additional requirements, including additional testing requirements and the reporting of additional test results, of SpecificationA 6/A 6M apply.
