Electrodes for Creep Resisting Steels

CROMOTHERME

AWS: SFA 5.5 E8018-B1

Cromotherme is a basic coated hydrogen controlled electrode. Ideally suited for welding of creep resistant steels of similar composition used in power plants, boilers, oil refineries and chemical plants.

Precaution

1. Ensure the electrodes are dry. Re-dry the electrodes at 250-300°C for one hour.

2. Use short arc during welding.
