ERW Pipes Atmospheric Corrosion Resistant Steel SPA-H/SPA-C Welded Tubes JIS G3125
CORTEN A Steel is Corrosion Tensile Atmospheric Resistant Welded Steel Pipes and Steel Tubes
Application for Structural Pipes by Round/Square/Rectangle ERW Pipes
Can be used for exhaust pipes,water pipes,cooling system pipes pressure containing parts such as
economizers or other applications where corrosion resistance is important.
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.
The welded Pipes produced from Cor-ten Steel,with the atmospheric resistance steel,
For welded steel pipes,We can offer square tubes,Round tubes,Rectangle tubes
For seamless steel pipes,We can offer OD from 6mm till 158mm for structural Steel tubes.
