As you know, ASTM A572 covers five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars.Grades 42 [290], 50 [345], and 55 [380] are intended for riveted, bolted, or welded structures. Grades 60 [415] and 65 [450] are intended for riveted or bolted construction of bridges, or for riveted, bolted, or welded construction in other applications.
Pipes in Grade 50 is a very common steel grade in ASTM A572 specification and is widely applied.
