ER309LSi filler consists of 22–24% chromium, 12–15% nickel, and 0.8–1.8% silicon, with low carbon content to minimize carbide precipitation. Its tensile strength is usually 80 ksi, yield strength around 60 ksi, and elongation approximately 30%. The additional silicon enhances fluidity, arc stability, and wetting performance in MIG and TIG welding. This alloy shows great oxidation resistance up to 870 °C and effectively bridges metallurgical gaps when joining stainless steels to carbon steels. It maintains high toughness and avoids cracking, even when dealing with different thermal expansions.
