ER409CB-24 - Exocor ER409Cb 3/32" Stainless Steel TIG Rod

Professional Grade Exhaust Welding with Exocor

When you are working on custom headers, repairing a blown-out muffler, or fabricating a full stainless exhaust system, using the right filler metal is the difference between a permanent fix and a callback. The Exocor ER409Cb TIG Rod is the go-to choice for professional welders dealing with 409 stainless steel. Most modern vehicle exhaust systems are made from this grade of stainless because it handles heat well and resists rust better than mild steel. If you try to weld these pipes with a standard mild steel rod, the weld will rust out in no time. If you use a 308L rod, the weld might look pretty, but the difference in heat expansion can cause cracks down the road. The ER409Cb is the perfect match.

This 3/32" rod gives you excellent control over the puddle, allowing for precise bead placement on thin-wall tubing without blowing through. The 'Cb' stands for Columbium (Niobium), a special ingredient that stabilizes the weld and keeps it strong even after it's been cooked by exhaust gases day in and day out. It prevents the weld from rotting out from the inside, ensuring your custom fabrication lasts as long as the car does.

Exocor is known for consistent quality, meaning you won't be fighting with impurities or inconsistent diameters. These rods feed smoothly through your hand, allowing you to focus on your torch angle and travel speed. Whether you are a shop specializing in performance exhaust systems or a general repair technician fixing a catalytic converter flange, keeping a tube of Exocor ER409Cb in your rack ensures you are ready for any ferritic stainless job that rolls through the bay door. Get the right color match, the right thermal properties, and the right durability for automotive work.
