Електроди зварювальні Моноліт М-307

AWS А 5.4:Е307-15
EN ISO 3581-A-Е 18 8 Mn B 2 2
CONDITIONS OF USE
  • applied when welding in all spatial positions, except vertical from top to bottom, with direct current of reverse polarity (+ on the electrode)
SPECIAL PROPERTIES
  • the deposited metal is characterized by high heat resistance up to 850°С
  • surfacing coefficient: 13,0…13,5 г/А·год
  • consumption of electrodes per 1 kg of deposited metal: 1,3…1,5 kg
Universal austenitic electrode for various applications - welding of "hard-to-weld" steels, dissimilar welding, repair and maintenance, as well as surfacing of transition layers under wear-resistant layers. The deposited metal provides exceptionally high ductility and elongation along with excellent crack resistance. Good resistance to embrittlement at operating temperatures of up to 650ºC.
