Four Times the Corrosion Resistance
A588 steel is well known for its weathering ability. When exposed to external conditions, its corrosion-resistant properties become stronger, even when unpainted. A588 steel has four times as much corrosion resistance as carbon steel.
It is heavily used in a broad range of applications that include transmission and phone towers, freight cars, bridge and gusset plates, and housing enclosures. This steel also maintains an excellent strength-to-weight ratio, meeting the strength requirements of carbon steel while weighing much less.
Composition that Maximizes Strength
The strength of A588 contributes to its long lifespan, even when subjected to the harshest elements. It has a tensile yield strength greater than 46,000 psi and a tensile strength equal to or greater than 65,700 psi at break. This metal is also highly weldable, producing high-quality welded joints that remain strong throughout the lifetime of the structure.
The composition of A588 steel is made up of a mix of certain elements, commonly including:
97% – 98.2% Iron
0.40% – 0.65% Chromium
0.25% – 0.40% Copper
0.90% – 1.25% Manganese
< 0.040% Phosphorous
0.15% – 0.30% Silicon
< 0.050% Sulfur
00.020% – 0.10% Vanadium
