ASTM A572 Grade 42 and Garde 50 low alloy steel

ASTM A572 standard specification 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.

For A572 Gr42/50 steel applications, such as welded bridge construction,where notch toughness is important, notch toughness requirements are to be negotiated between the purchaser and the producer.
