1.1 This specification covers carbon and high-strength low-alloy steel structural shapes, plates, and bars, quenched and tempered alloy steel, and stainless steel for structural plates intended for use in bridges. Twelve grades are available in five yield strength levels as follows:
| Grade U.S. [SI] | Yield Strength, ksi [MPa] |
|
|
|
| 36 [250] | 36 [250] |
| 50 [345] | 50 [345] |
| 50S [345S] | 50 [345] |
| QST 50 [QST 345] | 50 [345] |
| QST 50S [QST 345S] | 50 [345] |
| 50W [345W] | 50 [345] |
| HPS 50W [HPS 345W] | 50 [345] |
| 50CR [345CR] | 50 [345] |
| QST 65 [QST450] | 65 [450] |
| QST 70 [QST485] | 70 [485] |
| HPS 70W [HPS 485W] | 70 [485] |
| HPS 100W [HPS 690W] | 100 [690] |
1.1.1 Grades 36 [250], 50 [345], 50S [345S], 50W [345W], 50CR [345CR], QST 50 [QST 345], QST 50S [QST 345S], QST 65 [QST 450], and QST 70 [QST 485] are also included in Specifications A36/A36M, A572/A572M, A992/A992M, A588/A588M, A1010/A1010M (UNS S41003), and A913/A913M respectively. When the requirements of Table 11 or Table 12 or the supplementary requirements of this specification are specified, they exceed the requirements of Specifications A36/A36M, A572/A572M, A992/A992M, A588/A588M, A1010/A1010M (UNS S41003), and A913/A913M. Product availability is shown in Table 1.
1.1.2 Grades 50W [345W], 50CR [345CR], HPS 50W [HPS 345W], HPS 70W [HPS 485W], and HPS 100W [HPS 690W] have enhanced atmospheric corrosion resistance (see 13.1.2). Product availability is shown in Table 1.
