Hello all My customer wants to change the material of large electrical riveted enclosures we make from GI (1.0226) sheets to Corten-A grade sheets (2-3mm). Personally I have not seen an enclosure or cabinet made out of Corten-A steel which is primarily used to make locomotive shell body or steel structures that require better corrosion resistance. Do you guys have some points on benefit of using GI over Corten-A. (The enclosures that we make are used in dynamic application in rolling stock). I am not able to find much technical stuff which would prove that GI (1.0226) is equivalent to Corten-A. Regards ..
