ASTM A242 Weathering Steel

ASTM A242 (COR-TEN® Steel)

ASTM A242 is a high strength low-alloy structural steel specification with improved atmospheric corrosion resistance and higher temperature resistance. This specification is normally applicable to steel plates through one-half inch in thickness. ASTM A242 is used primarily in the fabrication of

  • Industrial air pollution stacks
  • Air Ducts off pollution control equipment
  • Water tanks

ASTM A242 can withstand sustained temperatures to 800F.

The atmospheric corrosion resistance of A242 is substantially better than that of carbon steels such as A36 and A572-50 with or without copper addition. When properly exposed to the atmosphere, A242 is suitable for many applications in the unpainted condition.

 

ASTM A242 has a 50ksi minimum yield strength and a 70ksi minimum tensile strength
