    ER 309L TIG inox, 50 units

    Reliable joints for high-performance exhausts

    If you're looking for a solid solution to weld stainless steel to carbon steel in high-performance exhaust systems, this pack of 50 ER 309L TIG inox filler rods is exactly what you need. Its behavior under heat and expansion makes it a popular choice in motorsport fabrication and custom builds.

    Technical specifications

    • Length: 39.37"
    • Available diameters: 0.039", 0.047", 0.063", 0.078"
    • Chemical composition (approx.): 24% Chromium (Cr), 13% Nickel (Ni)
    • Carbon content: max 0.03%
    • Classification: AWS A5.9 / SFA-5.9 ER309L

    Recommended applications

    • Exhaust systems: ideal for joining stainless to mild steel, with strong thermal and corrosion resistance.
    • Dissimilar joints: suitable for assemblies using metals with different thermal behaviors.
    • Repairs: perfect for fixing or reinforcing tubes exposed to constant thermal changes.

    Key benefits

    • Crack resistance: low carbon content prevents carbide precipitation and increases durability.
    • Thermal tolerance: maintains weld stability through thermal cycles.
    • Compatibility: works well with 304, 316 stainless steels and mixed-metal bases.

    Why choose ER 309L over ER 308L?

    While ER 308L is meant for similar stainless steels, ER 309L is the right choice when welding stainless to carbon steel. Its higher chromium and nickel levels offer better expansion handling and crack resistance. This makes all the difference in exhaust fabrication where thermal shifts are constant.

    Final consideration

    For difficult or unknown base metals, ER 312 may be an alternative. Still, for most performance exhaust projects, ER 309L TIG inox, 50 units, is the most reliable and consistent choice.
