Voestalpine Böhler Welding  |  Wire electrodes high-alloyed  |  Thermanit 309L Si

Thermanit 309L Si wire electrodes are high-alloy welding wires specifically designed for welding stainless steels and dissimilar metals. The alloy's high chromium and nickel content provides excellent corrosion and heat resistance. The addition of silicon improves weldability and melt pool flowability, resulting in smoother weld seams and reduced spatter. Typical applications include the chemical industry, petrochemical sector, and power plant construction, especially for welding transition layers between unalloyed or low-alloy steels and high-alloy stainless steels. Our service includes fast delivery and technical support.
