Key Characteristics of A588 Steel:

Applications: Commonly used in bridges, railcars, containers, and building construction.

Grades: Includes Grades A, B, C, and K, which are "silicon killed" for improved quality.

Shapes: Available in plates, sheets, wide flange beams, channels, and angles.

Corrosion Resistance: Offers enhanced atmospheric corrosion resistance, often used in bare, unpainted conditions.

Strength: Features a minimum yield strength of 345 MPa and minimum tensile strength of 485MPa for thicknesses up to 4 inches.

 

Common Uses:

Outdoor Structures: Sculptures and buildings where a rustic appearance is desired.

Infrastructure: Highway bridge girders and pedestrian bridges.

Industrial: Shipbuilding and shipping containers.

 

 

What is ASTM A588 material?

A588 is a type of weathering steel that's renowned for its exceptional corrosion resistance. With its unique ability to form a protective rust-like surface, it eliminates the need for additional coatings, reducing maintenance costs. ASTM A588 is also referred to as Corten® and covers structural shapes, plate, and bar.

 

What is A588 steel equivalent to?

ASTM A588 is a high-strength, low-alloy (HSLA) weathering steel with key international equivalents including Cor-Ten B, EN 10025-5 S355J2W/J0W, JIS G3114 SMA490BW/AW, and GB/T 4171 Q355NH. These materials offer superior atmospheric corrosion resistance for structural applications like bridges, buildings, and facades, typically providing a yield strength of
