ASTM A572 steel Specification refers to High-Strength Low-Alloy Steel Plate for structural building, among the 5 steel grades of 42, 50, 55, 60 and 65, Grade 50 is one most common steel in applications where need more strength and less weight, use steel plate of this grade other than ordinary carbon steel will make the steel structure with same steel strength but lighter weight.
There are five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars.
Grades 42 [290], 50 [345], and 55 [380] are best for riveted, bolted, or welded structures.
Grades 60 [415] and 65 [450] are best for riveted or bolted construction of bridges, or for riveted, bolted, or welded construction in other uses.
For higher strength and lower weight, consider Advanced High-strength Steels.
Formability: % Elongation: Basic, 17-24%
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
