Carbon
Plate- ASTM A 588
Standard specification for High-Strength Low-Allow
Structural Steel with 50 ksi Minimum Yield Point
First issued in 1968
This specification covers high-strength low-alloy structural
steel shapes, plates, and bars to be used for construction of
bridges, buildings, and other structures.
Atmospheric corrosion resistance of this grade in most environments
is substantially better than that of ordinary carbon structural
steels. When properly exposed to the atmosphere, this steel can
be used unpainted for many applications.
This grade must be made
to a fine grain practice. General requirements for delivery
Material shall conform to the requirements of ASTM A 6.
Chemical Requirements (plate only)
This specification allows for four different grades. Most
producers today choose to make Grade A, unless otherwise
specified.
Single values are maximums. Subject to product analysis tolerances
in ASTM A 6.
Tensile Requirements (plate only)
*Adjustments to elongation requirements may apply depending
on plate width. These values are for plates 96” wide
as rolled
