EI 312BLUE is a rutile coated stainless steel electrode for joint welding of different steels and for coating applications on ferritic steels. The ferritic-austenitic Cr-Ni alloy weld metal contains about 50% delta-ferrite and is scale resistant up to +1100°C. Due to its high crack resistance, it is suitable for joint welding of low weldability steels and for buffer layer applications prior to hardfacing on crack sensitive steels. It is especially used in crack repair, buffer pass applications, repair of eaten or cracked threads and buffer layer applications of cutting blades on mold and tool steels. It is also suitable for welding galvanized steels. EI 312BLUE provides superior performance when joining different steels, welding tool steels, manganese steels and spring steels. It can be welded with both AC and DC current, has a fine metal drop transition and ensures good fusion with base metal surfaces. It is characterized by soft melting, good seam appearance and easy to clean slag.
EI 308MA is a special rutile-type electrode designed for welding high-temperature stainless steels such as Outokumpu 253 MA and EI 308MA. These steels and filler metals, used in furnaces, combustion chambers, and burners, provide exceptional resistance to oxidation up to 1100°C. The chemical composition of EI 308MA is optimized to produce a weld metal with high crack resistance. These steels typically form a thick oxide layer during welding or hot rolling, and oxidized plates and welds must be cleaned before welding. The electrode offers easy arc initiation and re-ignition, features fine droplet transfer, and ensures good fusion with the base metal. The slag is easy to remove.It demonstrates excellent resistance to corrosion at high temperatures but is not designed for aqueous corrosion resistance.
Rutile coated electrode for joining dissimilar steels, depositing buffer layer before hardfacing and claddings on ferritic steels. The weld metal consists of austenitic Cr-Ni-Mn steel with possible small amounts of delta ferrite. The weld metal is highly crack resistant and therefore suited for joining difficult to weld steels and depositing stress relaxing buffer layers on crack sensitive base metal prior to hardfacing deposits. Weld metal work hardens by impact and pressure. Suitable for armour plates, high-manganese steels, rails, cross-overs, crane wheels, idlers, which are subjected to dynamically loading, pressure, impact and abrasion. It is non-scaling up to 850°C and highest operating temperature for dissimilar steel joints is 300°C. In the case of higher temperatures, use ENI 422 electrodes. Easy to use in positional welding and possible to use equally well both with AC and DC.
