Carbon Plate- ASTM A 516
Standard specification for Pressure Vessel Plates
Carbon Steel, for Moderate and Lower Tempeature Service

First issued in 1964

This specification covers carbon steel plates intended primarily for use in welded pressure vessels where improved notch toughness is important. It allows for four different strength levels. The most common is Grade 70.

This grade must be killed and made to a fine grain practice. Plates over 1-1/2” thick must be normalized. Additionally, when impact (notch toughness) tests are required on plates up to 1-1/2” thick, the plates must be normalized.

General requirements for delivery
Material shall conform to the requirements of ASTM A 20.

Chemical Requirements (plate only)

Chemical Requirements

Single values are maximums. Subject to product analysis tolerances in ASTM A 20.
*These are unspecified elements, which may be present but are limited to these values.

Tensile Requirements (plate only)

Tensile Requirements

*Adjustments to elongation requirements may apply depending on plate thickness. See ASTM A 20.

Notch Toughness
For those applications requiring impact tests, supplementary requirement S5 is available. Generally available impact test specifications for this supplement are provided in ASTM A 20, Table A1.15
