Electrodes for Creep Resisting Steels

CROMOTHERME-5L

AWS: SFA 5.5 E8018-B6L

Low carbon, low hydrogen, iron powder producing a weld deposit containing 5Cr –0.5Mo, which has excellent creep resistance at elevated temperatures up to 550oC. The weld metal displays excellent creep resistance with controlled hardness. The lower levels of carbon limit in weld metal ensuring higher ductility. Ideal for welding steels of similar composition. Typical applications include welding of 4 - 6% Cr steels in oil refinery, chemical plant and equipment.

Precaution

1. Re-dry the electrodes at 250-300 C for one hour, as per our standard recommended practice.

2. Use short arc and stringer bead.
