SAF Safer NF 510S description: SAFER NF 510S is a low hydrogen electrode allows welding with a stable arc and a very low spattering loss. It deposits a low hydrogen content weld metal. Excellent impact strength at low temperature (-46C). Suitable for unalloyed steels with low purity or higher carbon content, <0.4%C, and for buffer layers. Very low hydrogen content after re-drying. Material to be welded EN 10025-3: S(P) 235-S(P) 420; GP240- GP 280; L245-L360.
