OK 74.78 (E9018-D1)

LMA AC/DC electrode suitable for welding high tensile steels used in low temperature
applications. Good notch toughness down to -40°C. Suitable for enclosed welding and cladding of rails, when
a hardness of ~ 250 HV is required. Also suitable for butt welding rails with tensile strength of 800-900
N/mm2.
Due to low moisture content in the coating, this electrode is suitable when preheating cannot be applied.
