CSS 309 S
High-efficiency dissimilar stainless steel electrode
Product description
High-efficiency (160%) synthetic electrode with rutilo-basic coating, depositing 24% Cr – 13% Ni refractory steel. Smooth melting without spattering. Good slag release, concave bead with fine striations.
Used when a high deposition rate is required. Welding of steels of the same composition. Particularly recommended as an undercoat before hardfacing and for heterogeneous assemblies (stainless steel with ordinary steel).
