SUNRISE 7018

  • Classification: AWS/ASME SFA-5.1 - E 7018
  • DIN 1913 - E 51 55 B 10
  • EN499 - E 42 6 B 42 H10

Application/Properties: Electrode for producing crack-free welded joints with good toughness properties even on steels having carbon content up to 0.4%. Weld metal recovery is approx. 120%. Good operating characteristics also in positional welding. Weld metal exhibits good toughness properties down to -60 C. Electrode is suitable for depositing buffer layers on steels having higher carbon content.

Suitable for:
Unalloyed structural steel: St33 to St52-3, St50-2 to St60-2.
Boiler Plates: HI, HII, 17Mn4.
Pipe Steels: to St52.4, St35.8 to 17Mn4, StE210.7 to StE360.7 including corresponding TM-grades.
Fine Grain Structural Steels: StE255 to StE355, WStE255 to WStE355, TStE255 to TStE355.
Shipbuilding Steels: A, B, D, E.
Cast Steel: GS-38 to GS-52.
