WELDING WIRES AND ELECTRODES | STAINLESS GROUP
EI 308L
GENERAL FEATURES
Rutile coated electrode for welding austenitic stainless Cr-Ni steels or cast steels, having an extra low carbon content, as well as stainless or heat resisting chromium steels or cast steels. Suitable for welding stainless steel tanks, valves, pipes and linings in chemical, food, beverage, pharmaceutical industries. For operating temperatures of up to 350°C, non-scaling up to 800°C. Possible to use equally well both with AC and DC. Easy arc striking and re-striking. Fine metal droplet transfer, good fusion of joint faces, finely rippled bead surface, easily removable slag.
EI 309L
GENERAL FEATURES
Electrode for joining dissimilar steels (austenitic steels to ferritic steels) and for austenitic claddings on ferritic steels. Weld metal consists of austenite with approx. 15% delta-ferrite. Claddings on unalloyed and low alloy steels are already corrosion resistant in the first layer. Highest operating temperature for joints between dissimilar steels is 300°C. In case of higher temperatures use ENI 422 electrodes. Fine metal droplet transfer, good fusion of joint faces, finely ripped bead surface, easy slag removal, easy arc striking and restriking.
EI 310
GENERAL FEATURES
Rutile type stainless steel electrode for welding heat resisting chromium and chromium-nickel steels as well as cast steels. Weld metal deposit is fully austenitic stainless steel, containing 25% chromium and 20% nickel. Suitable for welding heat treatment and industrial furnaces and equipments which are subjected to service temperatures up to 1200°C. Weld metal is non-scaling up to 1250°C. Especially it is resistant to hot crack. Exhibits high charpy impact energy at low temperatures. Weld metal is not corrosion resistant to sulphurous combustion gases. Possible to use equally well both with AC and DC.
EI 312
GENERAL FEATURES
Rutile type stainless steel electrode for joining dissimilar steels and depositing claddings on ferritic steels. The ferritic-austenitic Cr-Ni weld metal contains approximately 50% of delta-ferrite and is non-scaling up to 1100°C. It features high resistance to cracking and is therefore suited for joining difficult to weld steels and depositing stress-relaxing buffer layers on crack sensitive base metals. Especially used in crack repair and build-up of tool and die steels, rebuilding of worn or cracked gear teeth, buffer layer on cutting blades. Suitable for welding galvanized steel plates. Possible to use equally well both AC and DC. Easy arc striking and re-striking. Fine metal droplet transfer, good fusion of joints faces, finely rippled bead surface, easy slag removal.
EIS 316
GENERAL FEATURES
Rutile type, high recovery (160%) stainless steel electrode for welding 19Cr/12Ni/2-3Mo austenitic stainless steels to mild steels and low alloyed steels and also for surfacing applications on such steels. Weld metal deposit is austenitic-ferritic stainless steels. Possible to use equally well both with AC and DC. High current carrying capacity, since core wire is not made of stainless steel.
