CORTEN A Steel is Corrosion Tensile Atmospheric Resistant Welded Steel Pipes and Steel Tubes
Cor-Ten A atmospheric corrosion resistant welded pipes/ERW Steel Tubes
COR-TEN A Steel is atmospheric corrosion resistant steel,Corrosion-Tensile Steel,high strength steel
The purity of the steel of fine grade austenitic quality and the addition of special alloys, provide this steel ,
excellent mechanical characteristics, even at high temperatures and self-passivating properties when exposed to
corrosive agents present in urban atmosphere. This property allows this steel to face down corrosion for longer
periods when compared to common steel, even if not painted.
Chemical Compostion:
Carbon, C <= 0.120 %
Chromium, Cr 0.500 - 1.25 %
Copper, Cu 0.250 - 0.550 %
Manganese, Mn 0.200 - 0.500 %
Nickel, Ni <= 0.650 %

Similar Steel grade:CORTEN A Steel,SPA-H JIS G3125,GB/T4171 09CuPCrNi-A,
APPLICATIONS - The mechanical characteristics and the resistance to atmospheric corrosion make this steel, the best
product for the fabrication of agricultural vans and railway wagons, structures of bridges, water pipes, fans, chimneys
and boilers.
HOT FORMING - This operation may be normally carried out in a temperature range of 800 °C to 1050 °C. If it is
required to use a different temperature, it is advisable to carry out a normalizing treatment at the end.
