AWS A5.4: E309LMo-16 | DIN EN ISO 3581-A: E 23 12 2 LR 12 Rutile Coated | Mo-Alloyed | Cracking and Corrosion Resistant StarBlaze Prime 309LMo is a low carbon rutile-basic type stainless steel electrode alloyed with 23Cr, 13Ni, and 2.5Mo, containing 15–25% ferrite in the weld metal. It is designed for welding AISI 309 and 316L stainless steels, and for dissimilar joints between stainless and mild steels. Commonly used as a buffer layer before 316L cladding or as a universal electrode in maintenance jobs, it offers smooth arc behavior, self-peeling slag, and excellent resistance to cracking, oxidation, and corrosion. Available Packs- Dimensions: 2.40 mm x 350 mm, 2.50 mm x 350 mm, 3.15 mm x 450 mm, 3.20 mm x 450 mm, 4.00 mm x 450 mm, 5.00 mm x 450 mm

AWS A5.4: E309Mo-16 | DIN EN ISO 3581-A: E 23 12 2 R 12 Rutile Coated | Mo-Alloyed | High Crack and Corrosion Resistance StarBlaze Prime 309Mo is a rutile-coated stainless steel electrode alloyed with 23Cr, 12.5Ni, and 2.5Mo, designed for welding AISI 309 and 316 stainless steels as well as dissimilar joints involving mild steel. It serves effectively as a buffer layer prior to 316 cladding and performs well in applications demanding both corrosion and crack resistance. The arc is smooth and spatter-free, producing a clean bead with easy slag removal and minimal post-weld cleanup. Available Packs
