and similar alloyed austenitic steels.

Processing instructions
Clean the weld areas. Re-dry at 350 °C / 1 h. When welding, adjust the heat control to the component, its material and dimensions. When welding similar alloys, limit the interpass temperature to 150 °C. Use wire brushes made of austenitic CrNi steels.
Welding positions: all except PG (f)
Current type: = (+) or ~
