A588 Corten® High Strength Low Alloy Steel
Corrosion-resistant ASTM A588 steel weathering plate, also referred to as Corten® steel is a heavy-duty material that provides a protective and aesthetically pleasing rust-like appearance when exposed to atmospheric conditions. A588 steel weathering plate offers all the advantages of ASTM A572-50. But, it is produced with elevated levels of copper to add advanced corrosion resistance and longer life in applications where element exposure is a crucial factor.
A588 Weathering Steel Plate Benefits
There are several benefits associated with A588 Corten steel plate that allow it to be used for industrial applications throughout the world. A588 weathering steel plate benefits include:
- Low maintenance
- Cost savings
- Speed of construction
- Safe
- Environmentally friendly
- Aesthetically appealing
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
Typical Uses
A588 Corten® steel is often used in unpainted applications that require advanced corrosion resistance, exposure to elements, and enhanced aesthetics. A588's self-repairing, natural oxide patina dramatically reduces maintenance, providing greater longevity for industries worldwide. The applications that benefit the most from A588 Corten® include the following:
- Bridges
- Utility poles
- Highway structures
- Guardrails
- Buildings
