Plate- ASTM A 572
Standard specification for High-Strength Low-Allow
First issued in 1966
This specification covers structural shapes, bars, sheet piling,
and plate to be used for construction of bridges, buildings,
and other structures.
For certain applications, notch toughness may be an important
requirement and should be addressed at the time the order is
This grade has higher tensile and yield strengths resulting
from the addition of small amounts of one or more alloying elements.
The choice of alloying element, whether columbium, vanadium,
nitrogen, or a combination of these is at the option of the producer
unless otherwise specified.
General requirements for delivery
Material shall conform to the requirements of ASTM A 6.
Chemical Requirements (plate only)
values are maximums. A maximum of manganese of 1.50% is permissible,
with an associated reduction of the carbon maximum of 0.03%.
Subject to product analysis tolerances in ASTM A 6.
This specification allows for four different types of alloy
content to achieve the required strength levels. Most producers
today choose to make Type 2, unless otherwise specified.
Tensile Requirements (plate only)
to elongation requirements may apply depending on plate width.
These values are for plates 96” wide as rolled.
