A516 Pressure Vessel Carbon Steel Plate

A516 Pressure Vessel Carbon Steel Plate

This specification, ASTM A516, covers carbon steel plates used primarily in welded pressure vessels where improved notch toughness is important. The plates are available in four grades, based on different strength levels: Grades 55, 60, 65, and 70. The most common is Grade 70, or A516-70.
