A588 is a high strength, low alloy steel plate that was developed for use cases demanding higher strength and a longer life cycle. A588 is known for its atmospheric corrosion resistance thanks to a natural patina of rust that forms when exposed to outdoor weather conditions.
Advantages/Disadvantages
The biggest advantage to A588 is its atmospheric corrosion resistance for which it was specially formulated. It is substantially better than other structural steels like A36 or A572.
