A516 Steel Plate

Precision Grinding is your source for ASTM A516 steel plate products and shapes cut to size, ground, machines and processed into steel parts.

This specification covers carbon steel plates intended primarily for service in welded pressure vessels where improved notch toughness is important. A516 plates are available in four grades: Grades 55, 60, 65, and 70, according the different strength levels.

A516-70 Steel Plate

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 play a vital role in a variety of demanding applications, including oil and gas and power generation.

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.

Common Uses of A516 Steel Plate

Example applications include: Rail car tanks, manways, sump applications, car heads and shells.
