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.

Chemical Requirements

Single values are maximums. Subject to product analysis tolerances in ASTM A 6.

Tensile Requirements (plate only)

Tensile Requirements

*Adjustments to elongation requirements may apply depending on plate width. These values are for plates 96” wide as rolled
