Advanced Metallurgy for Critical Stainless Applications

The ESAB OK Autrod 316LSi is a premium quality, continuous solid corrosion-resistant chromium-nickel-molybdenum wire designed for welding austenitic stainless alloys of the 18% Cr - 8% Ni and 18% Cr - 10% Ni - 3% Mo types. This specific alloy formulation, classified as ER316LSi, is engineered with a higher silicon content than standard 316L wires. The increased silicon (typically 0.65-1.00%) significantly lowers the surface tension of the molten weld pool, resulting in vastly improved wetting action, a flatter bead profile, and smoother tie-ins at the weld toes.

Metallurgically, the wire features a low carbon content (denoted by the 'L'), which is critical for minimizing the risk of carbide precipitation and subsequent intergranular corrosion, particularly in the heat-affected zone (HAZ). The addition of Molybdenum enhances the alloy's resistance to pitting and crevice corrosion, making it an excellent choice for environments containing chlorides or dilute acids. This wire is widely utilized in industries requiring high sanitary standards and corrosion resistance, such as the chemical processing, food and beverage manufacturing, and pharmaceutical sectors.

The ESAB OK Autrod 316LSi exhibits good general corrosion resistance and is suitable for joining stabilized and non-stabilized steels of the Cr-Ni-Mo type. It provides excellent mechanical properties, including high tensile strength and ductility, ensuring structural integrity in demanding fabrication projects. The wire is designed for use with Argon-based shielding gases, typically mixtures containing small amounts of Oxygen or Carbon Dioxide to stabilize the arc.
