-
Is 316L filler wire and 316L welding rod the same thing?Yes — the same ER316L is consumable in different forms: spooled wire for MIG and straight rods for TIG. Superon supplies both SUPERMIG 316L and SUPERTIG 316L.
-
Which welding rod should I use for 316 stainless steel?ER316L is the standard match for 316 and 316L base metal. Its molybdenum content gives the weld the same pitting and chemical corrosion resistance as the parent metal.
-
What is the difference between 308L and 316L filler?Both are low-carbon austenitic fillers; 316L adds molybdenum for higher pitting and chemical-corrosion resistance, so it is used on 316 base metal and in chemical or marine service, while 308L suits 304/304L.
-
Can 316L be used for MIG and TIG?Yes. SUPERMIG 316L runs on DC+ and SUPERTIG 316L on DC−, both to AWS ER316L, with tensile strength ≥510–520 N/mm².
-
What diameters and packaging is 316L available in?SUPERMIG 316L is supplied on SD/BS spools (up to ~15 kg) and in drums of 100–250 kg; SUPERTIG 316L is supplied as filler rods.
-
What industries use 316L filler wire?Chemical and petrochemical, marine and offshore, food and pharmaceutical, heat exchangers, pressure vessels and stainless piping — anywhere high corrosion resistance is required.
