[MW:12731] MW: 12727- May E8018-C1 substitue E8018-G to weld Corten Steel

By Materials & Welding
Hi Ghrab,
 
Corten is primarily a Copper added steel for weathering (atmospheric corrosion)  resistance, It comes in few grades,namely Coten -A & Corten-B. The default welding electrode which matches the BM chemistry is E-8018-W.
 
8018-C1 is (2.5%Ni) electrode, overallyed for Corten grades, not matching the BM chemistry. If the environment contains a lot of pollutants, there may be atmospheric corrosion overperiod of time.
 
Please find the data sheets for your help.
 
Thanks.
