Abracrom 309L
Rutile type stainless steel electrode
Description & applications
Low carbon rutile-basic electrode with an austenitic stainless steel deposit containing 15% ferrite- for welding dissimilar steels as stainless steels to low alloyed steels- also suitable for welding high temperature steels and as buffer layer before hardfacing- repairing of machine parts for civil engineering. First layer on construction steels for 18/8 cladding...-soft fusion-nice aspect of the bead. Self releasing slag.
