Re: [MW:31078] API 582

Hi,

Since this is P.No.1,Low temperature material, why do you go for ER80S-Ni1 ? Its used for weathering steel and corrosion resistant applications. It can be used to weld SA350, LF5 (P.No.9A) which is 1.5Ni steel

SA350, LF2 and SA333 Gr.6 are C-Mn-Si steel (P.No.1), for this ER70S2 or ER70S-6 are fine. Electrode E7018-1

Thanks& Regards,

Thanks for your response.

Please explain to me why I can't use ER80S-Ni1 for AWS 5.28 GTAW process according to the table - A1 API 582. 

Thanks
