A709 GR.36 CARBON STEEL H BEAM refers to a high-strength, low-alloy (HSLA) structural steel plate that conforms to the ASTM A709 specification commonly used in bridge construction. A709 provides high tensile and yield strength, making it suitable for various bridge components, such as girders, trusses, and other structural elements.
A709 GR.36 CARBON STEEL H BEAM CHEMICAL COMPOSITION
The following composition properties are ASTM specifications for the ASTM A709 grades. Note that the composition of chemicals ranges depending on the thickness of the material.
| GRADE 36 | |
| CARBON MAX | 0.25-0.27% |
| MANGANESE* | ... |
| PHOSPHORUS MAX | 0.030-0.040% |
| SULFUR MAX | 0.030-0.050% |
| SILICON* | 0.40% MAX |
| COPPER MIN | 0.20% |
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 A6/A6M for information on weldability.
