The F900-11(2017) steel grade is a high-strength, low-alloy structural steel that is commonly used in construction and engineering applications. It has a chemical composition that includes elements such as carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, vanadium, and boron.
The mechanical properties of F900-11(2017) steel grade include a minimum tensile strength of 900 MPa (megapascals), a minimum yield strength of 800 MPa, and a minimum elongation of 12%. It also has good toughness and weldability, making it suitable for structural applications in which high strength is required.
The F900-11(2017) steel grade is commonly used in the construction of bridges, buildings, and other structures where high strength and durability are critical. It is also used in the manufacturing of heavy machinery, equipment, and vehicles, such as cranes, excavators, and trucks.
The F900-11(2017) steel grade is specified by the ASTM International standard number A709/A709M-18. This standard provides the requirements for structural steel for bridges, including the F900-11(2017) grade.
Overall, the F900-11(2017) steel grade is a high-strength steel that offers excellent mechanical properties and is suitable for a wide range of applications in construction and engineering. Its chemical composition and mechanical properties make it a reliable choice for structures and equipment that require superior strength and durability.
