ASTM A709-50W Weathering Steel

ASTM A709-50W

ASTM A709-50W is a standard specification for structural steel primarily in the fabrication of steel bridges. ASTM A709-50W covers high strength, low allow steel structural shapes, plates and bars. The atmospheric corrosion resistance of this steel in most environments is substantially better than carbon steel with or without copper addition. ASTM A709-50W shall have an atmospheric corrosion index of 6.00 or higher. When properly designed and exposed to the atmosphere, A709-50W is suitable for many applications in the bare (unpainted) condition such as:

  • Pedestrian Bridges
  • Highway Bridge girders and other bridge components
  • Railroad bridges and overpasses

ASTM A709-50W has a 50ksi minimum yield strength and a 70ksi minimum tensile strength.
