Corten A A588 steel is a kind of high-strength low-alloy structural steel(HSLA) with atmospheric corrosion resistance. ASTM A588 steel covers excessive-electricity low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction however intended ordinarily for use in welded bridges and homes in which savings in weight or brought durability are vital. The atmospheric corrosion resistance of Corten A A588 steel plate in most environments is notably better than that of carbon structural steels with or without copper addition. Corten A A588 Steel Chemical Composition (%)
Mn: 0.8 - 1.25 %, Cr: 0.4 - 0.65 %, Si: 0.3 - 0.65 %, Cu: 0.25 - 0.4 %, V: 0.02 - 0.1 %
Difference between A588 Grade A and S355J2W Steel
This A588 Grade A
material develops a patina with increased resistance against the atmospheric corrosion in comparison with non-alloyed steels. Due to its restricted chemical composition, S355J2W STEEL has a better weldability compared to respective steels produced according to EN 10025-5. Corten A A588 steel is a weathering steel and was developed to avoid having to paint steel for protection. Features of Corten A A588 Steel Plate
Corrosion-resistant, high-strength, low-alloy steel plate.
Available in three grades: A, B and K.
Often referred to as Corten or Weathering steel.
Ideal for welding, riveting or bolting in construction applications, primarily for bridges and buildings.
Suitable for many applications in bare or unpainted conditions when exposed properly.
Charpy test requirements may be requested.
May be certified to meet multiple specifications and/or standards on Mill Test Report, but guaranteed to be certified to meet ASTM A588 standards.
