HYW ER316L Stainless Steel MIG Welding Wire is a molybdenum-bearing, low-carbon (L) austenitic stainless MIG wire (18% Cr / 12% Ni / 2.5% Mo) for maximum resistance to pitting and crevice corrosion. The added molybdenum makes it the preferred filler for marine, chemical, pharmaceutical and food-grade environments, with low carbon for superior intergranular corrosion resistance.
Key Features
-
› Low-carbon (L) chemistry minimizes carbide precipitation and intergranular corrosion
-
› High-silicon formulation for smooth wetting, a stable arc and reduced spatter
-
› Molybdenum-bearing for superior pitting and crevice corrosion resistance
-
› Precision-wound layer spools for consistent, tangle-free feeding
Ideal Applications
-
› Welding 316 / 316L molybdenum stainless base metals
-
› Marine hardware, boat fittings and coastal structures
-
› Chemical, petrochemical and pharmaceutical processing equipment
-
› Food-grade tanks, piping and sanitary fabrication
-
› Applications demanding superior pitting and crevice corrosion resistance
