ASTM A847 (COR-TEN® Steel)
ASTM A847 is a high strength low alloy steel covering cold-formed welded square and rectangular tubing and pipe. The atmospheric corrosion resistance of this steel in most environments is substantially better than carbon steel with or without copper addition. ASTM A847 is intended for use, unpainted, in welded, bolted or riveted construction
of bridges and other structures where high strength and enhanced corrosion resistance are required. When properly designed and exposed to the atmosphere, A847 can be used bare (unpainted) for many applications.
