ASTM A572 is a High-Strength Low-Alloy, Columbium-Vanadium Structural Steel.
There are five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars.
- Grades 42 , 50 , and 55  are best for riveted, bolted, or welded structures.
- Grades 60  and 65  are best for riveted or bolted construction of bridges, or for riveted, bolted, or welded construction in other uses.
We will be glad to help you select the exact grade for your needs.
- Strength, Yield Strength ksi (MPa), Tensile Strength ksi (MPa): Strong, 60-80 (415-550)
For higher strength and lower weight, consider Advanced High-strength Steels
- Formability: % Elongation: Basic, 17-24%
For better formability consider Drawing Steel
- Joining – Very Good: 10/10
As a result, the most common welding methods can be used. A572 steel is also commonly bolted and riveted in structures.
- Corrosion Resistance – Good
Can be galvanized to slow rusting. For longer life in harsh chemical conditions, consider Galvanized or Coated Steel
- Chemistry – Alloyed with small amounts of Columbium and Vanadium
- Cost – Higher.
Good when thinner or stronger steels will add value.
