As rolled A516-70 plate

A516-70 plate is a carbon steel pressure vessel plate that offers an optimum combination of strength, weldability and notch toughness.

ASTM A516-70 Plate is also called out as ASME SA516-70.  This steel plate grade is a medium carbon alloy that also contains amounts of manganese, phosphorus, sulfur, and silicon. ASTM A516 is primarily used for service in welded pressure vessels where improved notch toughness is required. As rolled A516-70 plate is typically found in moderate and lower temperature applications. A516 is sometimes called PVQ516.

Supplementary testing such as charpy impacts, ultrasonic examination and carbon equivalency are available. All plates over 1-1/2” thick are required to be normalized. A516 grade 70 material  is the most popular pressure vessel grade of steel plate in the industry. It is produced in grades 55, 60, 65 or 70.  The most common is A516 Grade 70 or called out A516-70.
