Description:
Cromarod 316L is a rutile flux coated AC/DC electrode intended for welding the low carbon,
molybdenum alloyed, acid resisting austenitic stainless steels of similar composition (316L).
Operability is excellent with a smooth low spatter arc producing an exceptionally good weld bead
appearance. Fillet welds have a smooth surface, slightly concave profile with excellent toe line
blend-in and a self-releasing slag. The electrode is all positional up to and including 3.25 mm
diameter. Cromarod 316L is suitable for welding normal carbon 316 type grades and also Nb or Ti
stabilised steels, provided service temperatures are below 400 °C. For 316 material grades used at
elevated temperatures, Cromarod 318 is recommended.
