Ratna R-680

For joining difficult-to-weld steel and dissimilar steels such as dies, tool and spring steels and joining steel to unknown composition, also used as cushion layer on difficult steels to weld steel before depositing final hard facing layer.

A unique austenitic-ferritic low heat input welding electrode for combination of high tensile strength and weldability. Electrode is controlled grain structure and ferritic. Weld metals offers superb combination of high strength, crack resistance, ductility and weldability.
