HYW ER316L Stainless Steel MIG Welding Wire

$17.31 Oferta

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

Available Sizes & Recommended Amperage

Diameter Recommended Amperage
.030" (0.8 mm) 40 – 145 A
.035" (0.9 mm) 50 – 180 A
.045" (1.2 mm) 75 – 350 A

Recommended amperage ranges are general guidelines; optimal settings vary with base-metal thickness, joint design, shielding gas, and welding position. Store wire in a dry location to prevent oxidation and ensure smooth feeding.

⚠ WARNING: This product and the fumes and gases produced when welding it can expose you to chemicals including nickel and hexavalent chromium compounds, which are known to the State of California to cause cancer, and manganese, which is known to cause birth defects or other reproductive harm.
