Product Overview
This ER308L TIG welding filler wire (1.6mm / 1/16") is precision-engineered for fusion welding of 304 and 304L austenitic stainless steel. The low-carbon "L" grade formulation minimizes carbide precipitation during welding, delivering superior corrosion resistance and reducing the risk of intergranular corrosion in the heat-affected zone — making it the go-to filler metal for food-grade, chemical processing, and general fabrication stainless steel applications.
Key Features
- Material Grade: ER308L stainless steel filler wire
- Diameter: 1.6mm (1/16 inch) — ideal for medium-thickness stainless sheet and plate
- Low Carbon Content: <0.03% carbon prevents chromium carbide precipitation, preserving corrosion resistance
- Compatible Base Metals: 304, 304L, 302, 321, 347 stainless steels
- Smooth Arc Characteristics: Consistent, spatter-free TIG (GTAW) welds with excellent bead appearance
- High Purity: Tight chemical composition control for consistent weld quality
- Straight Lengths: Typically supplied in 1m / 39-inch precision-cut rods

Why Choose ER308L 1.6mm TIG Wire?
Whether you're a professional fabricator or a hobbyist welder, this 1.6mm ER308L TIG filler rod offers the ideal balance of control and deposition rate for thin-to-medium gauge stainless steel. Its low-carbon composition makes it the industry-standard choice when welding 304-series stainless where post-weld corrosion resistance is critical — no sensitization, no rust bleed, just clean, durable, code-quality welds.
Recommended For: TIG (GTAW) welding processes using DCEN (Direct Current Electrode Negative) polarity with pure argon or argon-helium shielding gas.
Low carbon 19Cr/10Ni type filler rod recommended for TIG and oxy-acetylene welding of 304 and 304L stainless steels. Applications include welding of stainless steels of similar composition in dairies, power, chemical and fertiliser
plants, etc. where relatively mild corrosive attack can be expected.
