Products Description
A588 Corten Steel Plate is a weathering steel renowned for its exceptional corrosion resistance. It forms a unique rust-resistant protective surface without requiring additional coatings, thereby reducing maintenance costs.
ASTM A588, also known as Weathering Steel Plate, features a distinctive protective surface resembling rust when exposed to air. This natural oxidation process creates a barrier that inhibits further corrosion, eliminating the need for additional protective coatings.
ASTM A588 Hot Rolled Corten Steel Plate has a minimum yield strength of 50 ksi and a minimum tensile strength of 70 ksi. Weathering steel is not suitable for high-load components operating above 450 degrees Celsius.
Additionally, the weathered appearance of ASTM A588 steel is often considered aesthetically pleasing and is frequently used in architectural applications.
