$21.16 Oferta

ER316L Stainless Steel TIG Welding Filler Rod is a molybdenum-bearing low-carbon austenitic stainless steel filler rod for corrosion-resistant TIG (GTAW) welds. Supplied as straightened 36" (914 mm) cut lengths in 0.045", 1/16", 3/32", and 1/8" diameters and 1, 2, 5, and 10 lb packs, it matches 316 and 316L stainless and excels in chloride, marine, and chemical-service environments. Select your diameter and pack size above.

Key Features

  • › 2–3% molybdenum for superior pitting and crevice corrosion resistance
  • › Low-carbon (≤0.03% C) to resist sensitization and intergranular corrosion
  • › Designed to match 316 and 316L stainless base metals
  • › Excellent performance in chloride and marine environments
  • › Bright, clean, ductile weld deposit

Ideal Applications

  • › Welding 316, 316L, and 317 stainless steels
  • › Marine, coastal, and saltwater-service equipment
  • › Chemical, petrochemical, and pharmaceutical process piping
  • › Food and beverage processing equipment
  • › Pulp, paper, and other corrosive-service fabrication

Available Sizes & Recommended Amperage

Diameter Recommended Amperage
0.045" (1.2 mm) × 36" 40 – 90 A
1/16" (1.6 mm) × 36" 70 – 110 A
3/32" (2.4 mm) × 36" 100 – 160 A
1/8" (3.2 mm) × 36" 120 – 210 A

Recommended amperage ranges are general guidelines; optimal settings vary with base-metal thickness, joint design, tungsten selection, and welding position. Store filler rod in a dry location to prevent oxidation and ensure clean welds.

⚠ 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.
