ASTM A588 Grade A Equivalent Grade

High-strength, low-alloy weathering steel supplied to ASTM A588 / ASME SA588 specification. This material (equivalent to DIN WTSt 52-3 and EN A588) delivers enhanced atmospheric corrosion resistance and a minimum yield strength of 50,000 psi (≈345 MPa), enabling lighter, cost-efficient structural designs.

Key features

• Material type: Weathering (HSLA) steel, ASTM A588 series (Grade A available; Grades B, C and K also offered)
• Standards: ASTM A588 / ASME SA588 (equivalent to DIN WTSt 52-3, EN A588)
• Mechanical advantage: High yield strength for reduced section sizes and lower overall structure weight
• Corrosion performance: Designed for superior resistance to atmospheric corrosion (forms a protective patina in many environments)
