Vibrant Performance 29233 ER309L SS TIG Filler Wire 0.035in 0.9mm 39.5in 3lb Box

Vehicle Fitment

• Universal - not vehicle-specific; suitable for all TIG welding applications involving stainless steel, dissimilar metal joints, or stainless steel overlay work

Fitment Notes

• Ideal for joining mild steel to stainless steel (dissimilar metal welding)
• Suitable for exhaust fabrication, manifold building, turbo piping, and performance tube work involving stainless components
• Not recommended for high-temperature austenitic stainless applications above 700°F where ER308L or ER316L are preferred
• Requires 100% Argon shielding gas for TIG (GTAW) process

Features

• ER309L alloy - the industry standard for welding dissimilar metals including mild steel to stainless steel
• Low carbon content (max 0.03%) reduces the risk of intergranular carbide precipitation and weld corrosion
• Silicon additives improve weld pool fluidity (wetting action) and reduce cracking sensitivity
• High strength with good toughness across a wide temperature range
• Outstanding weld properties for clean, consistent, professional-quality beads
• Conforms to AWS A5.9 / ASME SFA A5.9 specifications
• Cost-effective 3 lb pre-pack - buy only what you need

Product Description

The Vibrant Performance 29233 is a 3 lb box of ER309L stainless steel TIG filler wire, sized at 0.035 in. (0.9mm) diameter with 39.5 in. rod lengths. ER309L is the most widely used stainless filler wire for joining dissimilar metals - most commonly mild steel to stainless steel - making it an essential consumable for exhaust fabrication, turbo manifold builds, and performance piping work where carbon steel flanges or collectors are welded to stainless tubing. Its low carbon content (max 0.03%) minimizes the risk of intergranular corrosion at the heat-affected zone, while silicon additives improve weld pool flow and reduce bead cracking.

Vibrant offers this wire in a cost-effective pre-pack format so builders can purchase the exact quantity needed without excess waste. This 3 lb box is ideal for larger fabrication runs or shops that regularly work with mixed-metal exhaust and induction systems. Conforms to AWS A5.9 / ASME SFA A5.9 and requires 100% Argon shielding gas.
