ASTM A572
ASTM A572
ASTM A572 is a specification produced by ASTM International for high-strength, low-alloy columbium-vanadium structural steel. It is widely used in construction, infrastructure, and heavy equipment due to its high strength, excellent weldability, and improved atmospheric corrosion resistance compared to conventional carbon steels.
Key Features
- High strength-to-weight ratio
- Good ductility and weldability
- Suitable for bolting, riveting, or welding
- Available in five grades: 42, 50, 55, 60, and 65
