The A416/A416M-17 steel grade is a high-strength, low-alloy steel commonly used in construction projects. It offers excellent mechanical properties, making it suitable for applications that require strength and durability.
The chemical composition of the A416/A416M-17 steel grade is as follows:
– Carbon (C): 0.20% max
– Manganese (Mn): 1.20% max
– Phosphorus (P): 0.030% max
– Sulfur (S): 0.030% max
– Silicon (Si): 0.15-0.55%
– Copper (Cu): 0.30% max
– Chromium (Cr): 0.20% max
– Nickel (Ni): 0.20% max
These elements contribute to the overall strength and toughness of the steel. The low carbon content helps to improve weldability, while manganese enhances the hardenability and strength. Phosphorus and sulfur are controlled to ensure good machinability and prevent the formation of detrimental phases.
In terms of mechanical properties, the A416/A416M-17 steel grade offers a minimum yield strength of 550 MPa (80 ksi) and a minimum tensile strength of 690 MPa (100 ksi). It has excellent ductility and toughness, allowing it to withstand heavy loads and external forces.
The A416/A416M-17 steel grade complies with the corresponding ASTM standard number A416/A416M-17, which sets the requirements for prestressed concrete steel strand. This standard ensures that the steel meets the necessary specifications for use in construction projects.
Overall, the A416/A416M-17 steel grade is a reliable choice for construction projects that require high-strength and durable materials. Its chemical composition and mechanical properties make it suitable for a wide range of applications where strength and durability are crucial factors.
