Hydrogen controlled iron powder Electrode for welding Creep-Resistant 1Cr-0.5Mo steels.
CLASSIFICATION : AWS/SFA-5.5: E 8018 B2
IS-1395: E55 BB 226Fe
CHARACTERISTICS : A medium heavy coated, hydrogen controlled, iron powder type, all position radiographic quality electrode to weld 1.25% Cr-0.50% Mo steel, having increased working efficiency. Electrode has properties of creep resistance up to 550°C.
APPLICATION :
1) Suitable to weld creep resistant steels like Cr-Mo pipelines and plates used in oil refinery.
2) Power plants, steam boilers.
3) Equipments subjected at high temperature in synthetic chemical units.
4) Repair of cast steel components.
5) Parts of automobiles & earthmoving machineries.
RE-DRY CONDITION : Re-Dry the electrode at 250°C for 1 hrs before use.
