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.
A588 steel was developed primarily for industries requiring outdoor structural steel solutions, wherever there is a need for a combination of lighter weight, higher durability, and exceptional corrosion resistance.
Grades A and B both have good material machinability.

ANSWER:
ASTM A588 is available in 3 grades, A, B, and K.
ANSWER:
With the addition of copper, nickel, and chromium alloys, ASTM A588 is specially designed for projects with high exposure to atmospheric conditions. In fact, its advantage over similar steels like A572 is its weathering ability. For that reason, A588 is also known as a weathering steel. The surface oxidation of weathering steel—what gives it its distinctive rusty appearance when unpainted—typically takes six months, but surface treatments can accelerate the oxidation to as little as a few hours.
ANSWER:
Because of its strong, innate resistance to corrosion, A588 can be used in its bare, or unpainted, condition.
ANSWER:
Cor-Ten® is a trade name for atmospheric corrosion resistant steel with the same specifications as A588. As it became more popular over the years, mills began to develop their own versions, at which point ASTM created standard specifications for it, what we now know as A588.
