Mig wire s/steel 309lsi 0.80mm (15kg)

ER309LSi is an AWS-classified stainless MIG wire with silicon addition, formulated for joining dissimilar metals — primarily 304/316 stainless steel to carbon or low-alloy steel — and for cladding or overlay applications. The low carbon chemistry reduces sensitisation risk. Requires Ar/2%CO2 or Ar/O2 shielding gas. The 0.80mm diameter suits thin-section and precision dissimilar metal welding. Supplied on a 15kg spool.
