Basic type electrode used for the welding of heat resisting steels containing 2¼ Cr - 1 Mo at elevated temperatures up to 600°C. Applications include piping, casting and boiler super heaters.
Features and Applications
Applicability in welding of heat-resisting steels containing 2% Cr - 1% Mn and similar alloys
Electrode with basic-type coating
Formation of more ductile and less hard weld metal due to low carbon content
Serviceability at temperatures of values up to 600 °C
Recommended pre-heating and post-heat treatment during welding processes
Requirement of re-drying for min. 2 hours at the temperatures between 300°C and 350°C
Vacuumed packed electrodes
