What is ASTM A588 steel plate?

A588 steel is high-strength, low-alloy structural steel designed to resist atmospheric corrosion. Its properties are endowed because of elements such as chromium, copper, nickel, and phosphorus, all of which resist rusting and other destructive weather conditions. The steel forms a stable patina with exposure to air and moisture, further resisting corrosion. Hence, it is highly suitable for outdoor applications.

This steel is largely used in civil engineering and architecture, coming with a tensile strength in the neighborhood of 70,000 psi (pounds per square inch) and a yield strength of about 50,000 psi, suitable for heavy-duty structural engineering. It is employed in building bridges, retaining walls, and facades, with an application in art installations and decorative work as well due to its rustic appearance.

What are the Properties of A588 steel weathering plate?

HSLA-approved A588 Corten steel provides the following properties:

• Tensile: 70 ksi min (4 inch and under), 67 ksi min (4-5) 63 ksi min (Over 5-8)
• Yield: 50 ksi min (4 and under), 46 ksi min (4- 5) 42 ksi min (Over 5-8)
• Elongation: 16 percent min in 8-inch 19 percent min in 2 inch (for plates wider than 24 inch) in sheet

What is STM A572-GR 50 Steel?

ASTM A992/ASTM A572-GR 50 is a high-strength low-alloy steel that is used in general structural applications when the structure will be riveted, bolted, or welded. ASTM A572-GR50 is Columbium-Vanadium Steel that offers a minimum yield of 50 KSI and is used whenever a cost savings from a weight reduction can be gained.

A588 vs A572-50

Generally, both A588 steel sheet and A572 steel plate belong to low alloy high strength steel / HSLA steel that is utilized primarily in structural applications such as bridges and buildings. But they also have much differences. The HSLA steel sheet A588 is designed for projects requiring atmospheric corrosion resistance. For HSLA steel sheet A588 VS A572 high strength steel plate, HSLA steel sheet A588 has advantage over A572 high strength steel plate in weathering ability. When properly exposed to the atmosphere, HSLA steel sheet A588 can be utilized in bare condition (unpainted), while A572 high strength steel plate is not suggested.

How to Choose between A588 Corten Steel and A572-50

• Choose A588 for bridges, highway signs, or architectural sculptures where the steel will be exposed to the elements and low maintenance is desired.
• Choose A572-50 for general construction, heavy equipment, or building frames where the material will be protected from the weather or cost-efficiency is the priority.
