ASTM A606 Plate

ASTM A606 Plate


ASTM A606 plate, a High Strength Low Alloy (HSLA) steel plate, is 20-30% lighter than carbon steel and exhibits up to four times the atmospheric corrosion resistance of common structural carbon steel. When it is exposed to external conditions, the steel plate develops a weathered orange-brown oxide that is resistant to corrosion, increasing its life and durability. It is weldable, formable, punchable, and machinable using the proper techniques.

Corten is a trade name associated with A606. This group of steel alloys under the name of Corten is also known as weathering steel due to its rust-like appearance when expoosed to weathering over time.


Appilications for ASTM A606 plate include:

  • Bridges
  • Telecommunications and transmission towers
  • Freight cars
  • Housings that require durability and a high strength-to-weight ratio
