  • Basic electrode for welding austenitic and acid-resistant steels.
  • Good impact strength and crack resistance.
  • For joining hardened, armored manganese steels with 13% Mn content and difficult-to-weld steels, without the need for preheating.
  • Recommended for joining stainless and carbon steels with low and medium carbon content.
  • The weld can be heat treated without loss of ductility.
  • Achieved hardnesses of 200 HV to 450 HV.
  • Used as a buffer layer in rock crushers (manganese steels) and in crack repair processes.
  • The use of this weld metal on difficult-to-weld sheets eliminates some of the problems associated with cracking of these steels.
