309L Stainless Steel TIG Rods

309L stainless steel TIG rods (classified as ER309L) are high-alloy filler metals designed for joining dissimilar metals and welding stainless steels to carbon or mild steel. With a higher chromium and nickel content than standard 308 or 316 fillers, 309L rods provide excellent crack resistance, strong weld integrity, and reliable performance in demanding fabrication environments.
