This specification covers carbon steel plates intended primarily for service in welded pressure vessels where improved notch and impact toughness is important. A516 plates are available in four grades: Grades 55, 60, 65, and 70, according the different strength levels. The most common grade, ASTM A516-70, is a medium carbon alloy designed for use in pressure vessels and boilers. Another trade name for A516-70 plate is PVQ Plate (Pressure Vessel Quality). Pressure vessel grades are vital in a variety of demanding applications, including oil and gas and power generation.

Typical applications include: rail car tanks, manways, sump applications, car heads and shells. It is a high strength metal, easy to fabricate and can be securely welded. A516-70 plate also has low corrosion properties. This standard has been approved for use by offices underneath the jurisdiction of the Department of Defense.
