ER308L TIG Filler Wire — 2.4mm (for 304/304L Stainless Steel)

Premium ER308L TIG filler wire, 2.4mm diameter, engineered for welding 304 and 304L austenitic stainless steel. Low carbon content ensures excellent corrosion resistance, smooth arc stability, and clean, spatter-free welds — ideal for food-grade, chemical, and structural stainless fabrication.

Full Product Description

ER308L 2.4mm TIG Filler Wire is a premium-grade tungsten inert gas (TIG) welding rod specifically formulated for joining 304 and 304L stainless steel base metals. With its low carbon ("L" grade) composition, this filler wire minimizes carbide precipitation during welding, significantly reducing the risk of intergranular corrosion — making it the go-to choice for professionals working in food processing, pharmaceutical, dairy, chemical, and marine industries.

Key Features

• Diameter: 2.4mm (3/32 inch) — suited for medium-to-thick section stainless steel welding
• Alloy Type: ER308L (low carbon stainless steel filler)
• Base Metal Compatibility: 304, 304L, 321, and similar 18-8 austenitic stainless steels
• Corrosion Resistance: High resistance to oxidation and inter-granular corrosion, ideal for stainless applications exposed to moisture and chemicals
• Smooth Arc Performance: Consistent feed and stable arc characteristics for clean, uniform weld beads
• Low Spatter: Produces minimal spatter for reduced post-weld cleanup
• Precision Straightened & Cut: Uniform straight lengths for consistent TIG welding performance
• Surface Finish: Bright, polished finish for easy visual inspection of weld puddle

Applications

• Stainless steel pipe and tube welding
• Food and beverage processing equipment
• Kitchen and commercial appliance fabrication
• Chemical processing tanks and vessels
• Marine and architectural stainless steel structures
• General fabrication and repair of 304/304L stainless components

Why Choose ER308L for 304 Stainless Steel?

304 stainless steel is one of the most widely used austenitic stainless grades, and ER308L filler wire is its matching consumable of choice. The low carbon content (typically =0.03%) prevents chromium carbide formation at grain boundaries during welding, preserving the base metal's corrosion resistance — especially critical in sanitary and food-contact applications where weld integrity cannot be compromised.

Recommended Welding Parameters

• Process: GTAW (Gas Tungsten Arc Welding / TIG)
• Shielding Gas: 100% Argon (or Argon/Helium blend for thicker sections)
• Polarity: DCEN (Direct Current Electrode Negative)
• Typical Current Range: 90–180A (depending on material thickness and joint design)
