Send Message Request a Quote

The E312-16 welding electrode is the dual-phase steel rod with lime-titania coating. Due to 40% ferrite content contained in this filler material, our welding electrode provides crack resistance and weldability. This kind of metal welding rod is applicable for welding of high carbon steel, tool steel, high temperature steel, armour steel and dissimilar steel, etc.
