Rutile high-alloy extra-low carbon electrode (ELC) for non-stabilized and stabilized chromium - nickel steels resistant to atmospheric corrosion of the 18 Cr/8 Ni type. Resistant to grain disintegration of operating temperatures up to 350°C. Smooth running. Good striking and restrinking. Regular appearance, finely rippled, smooth junction. Easy slag removal.
Materials of application
All chromium-nickel steels with low or medium C content, as well as titanium and niobium stabilized chromium-nickel steels of the 18 Cr/8 Ni type, e.g. material No 1.4300, 1.4301, 1.4306, 1.4541, 1.4543, 1.4550, AISI 302, 304, 304 L, 321, 347.
