JIS G3114 SMA400BW Corten Sheet
SMA400BW is a Japanese standard corrosion-resistant steel plate, which implements JISG3114-2004 standard. SMA400BW is mainly used in the manufacture of containers, railway vehicles, oil derricks, harbor buildings, oil platforms and chemical and petroleum equipment containing hydrogen sulfide corrosive media such as containers and other structural components.
SMA400BW corten steel material heat treatment process: Heat treatment can be carried out according to specific applications and needs: normalized, tempered, normalized rolled or delivered without heat treatment.
