The Hyundai S-309L.16 3.2mm electrode is engineered for welding dissimilar metals, such as joining stainless steel to carbon or low-alloy steels. It is also suitable for under-layer welding on cladded stainless steel grooves. This lime-titania type electrode offers excellent usability, with an all-weld metal composition that includes extra-low carbon and a high delta ferrite content, ensuring superior corrosion and heat resistance.
