They are known for their high strength as well as lower composition of alloy throughout its structure. Their wide use is primarily due to these properties.

Additionally, they have very high yield and tensile strengths, as well as the ability to elongate very easily. It also exhibits a high resistance to stress related corrosion, as well as excellent protection against corrosion cracking and pitting. Its excellent corrosion resistance and abilities to inhibit oxidation, toxic gases, reduction, and reactive chemicals are some of its many corrosion-related advantages. Additionally, it is able to resist extremely hot conditions and extreme temperatures. This material is excellent for weldability and machinability. The material is ideally suited for joining and bending. Highly rigid and tough, they can be bent and joined seamlessly. They are very tough and are able to withstand even the most severe conditions. It can be used in a number of varying weather conditions as well. Steel plates for weathering are available in various shapes including hot rolled, cold rolled, normalised, and even tempered. All of these products can be customized to meet your needs. Our products are also subjected to various tests, including destructive and non-destructive tests, like firmness tests, impact tests, etc.

As a supplier of strong and durable ASTM A588 steel in a variety of shapes and forms,. stocks and delivers steel in a variety of forms. ASTM A588 steel is a high-quality, long-lasting product available in angles, channel and beams, steel plate, and bars.Among the world’s most vital structures, A588 can withstand the harshest conditions on the planet. A588 is an ASTM specification for high-strength, low-alloy structural steel shapes, including angles, channels, and beams. It also covers structural steel plates and bars and has improved corrosion resistance to atmospheric conditions. ASTM A588 is primarily used for:

  • Pedestrian Bridges
  • Highway Bridge Girders and other bridge components
  • Shipbuilding
  • Tanks
  • Railcars and Containers
  • Fencing
  • Sculpture

An A588 specification is primarily intended for use in unpainted environments, where savings in weight or added durability is important along with the longer life cycle due to its corrosion resistant properties and/or to achieve an aesthetically pleasing appearance.

A588 has a much higher atmospheric corrosion resistance than standard carbon steels like A36 and A572-50, whether copper is added or not. A588 is suitable for many applications in the unpainted state when correctly designed and exposed to the air.

The minimum yield strength and minimum tensile strength according to ASTM A588 are 50ksi and 70ksi, respectively.

Please note, weathering steels are not suitable for use in significant load-bearing members above 450 degrees Celsius.

Application Industries For Corten Steel ASTM A588 Grade B Plate & Sheet

The ASTM A588 specification for high strength low-alloy structural steel provides improved corrosion resistance for structural steel shapes like angles, channels, beams, as well as steel plate and bars. The A588 specification is intended mainly for use in welded bridges and other structures that are designed to achieve weight savings or increased durability in addition to corrosion resistance properties that yield a longer life cycle.

A588 has a significantly better atmospheric corrosion resistance than carbon steels like A36 and A572-50 with or without adding copper to it. When properly designed and exposed to the atmosphere, A588 is suitable for many applications in the unpainted condition.

FAQs for ASTM A588 Corten Steel Plates

ASTM A588 is a weathering steel, also known as Corten steel, prized for its superior corrosion resistance. It forms a protective, rust-like layer, eliminating the need for painting or other coatings and thus minimizing maintenance. This specification covers structural shapes, plates, and bars.

ASTM A588 Grade A weathering steel is similar to these international structural steel standards:

  • EN 10025-5: S355J0WP
  • JIS G3125: SPA-H
  • BS 4360: WR 50 A

ASTM A588 is a high-strength, low-alloy structural steel, whereas A36 is a carbon steel. This difference in chemical composition gives A588 superior corrosion resistance and higher strength, leading to a wider range of applications compared to A36.  Essentially, A588 is a more specialized and higher-performing steel than the more general-purpose A36.

A588 steel, with its copper, chromium, and nickel alloying, offers excellent atmospheric corrosion resistance. It’s also readily weldable, machinable, and formable, making it a versatile material for various construction projects.
