Typical applications and characteristics
GEMINI 309 L is a rutile extra low carbon coated electrode for welding corrosion resistant and heat resistant Cr and Cr-Ni steels. The high level of alloying elements makes this electrode also suitable for welding Cr and Cr-Ni steel to mild steel welding Cr-Ni clad steel. Very smooth weld with clean edge. Low spatter loss and excellent slag removability
