ASTM A709 Grade 50 steel is primarily used in:
Available dimensions for ASTM A709 Grade 50 steel:
| Thickness | Width | Length |
|---|---|---|
| 0.1875 to 3 inch | 72 to 120 inch | 240 to 1200 inch |
| Grade | Yield Strength (min) | Tensile Strength (min) | Corrosion Resistance |
|---|---|---|---|
| 36 | 36 ksi (250 MPa) | 58 ksi (400 MPa) | Standard |
| 50 | 50 ksi (345 MPa) | 65 ksi (450 MPa) | Enhanced |
| 50W | 50 ksi (345 MPa) | 70 ksi (485 MPa) | Improved |
ASTM A709 Grade 50 offers enhanced corrosion resistance compared to standard grades. The 50W variant provides improved atmospheric corrosion resistance, making it suitable for use in bare (unpainted) conditions in many environments.
ASTM A709 Grade 50 steel is excellent weldable and can be welded using conventional methods. It has fair machinability and formability, requiring more force for forming than plain carbon steels.At HL Steel Company, we offer high-quality ASTM A709 Grade 50 steel coils tailored for bridge construction and other structural applications, ensuring optimal performance and durability for your projects.
