Electrodes for Creep Resisting Steels

CROMOTHERME-5

AWS: SFA 5.5 E8018-B6 EN ISO CODE: 3580-A E CrMo5 B 4 2

Low hydrogen, iron powder electrode producing a weld deposit containing 5Cr - 0.5Mo, which has excellent creep resistance at elevated temperatures up to 550°C. Typical applications include welding of 4-6% Cr steels in oil refinery, chemical plant and equipment.

Precaution

1. Ensure the electrodes are dry. Re-dry the electrodes at 300°C for 2 hours.

2. Use short arc, low current and stringer beads.

NOTE : Low carbon version Cromotherme - 5L conforming to AWS : E8018-B6L is also available.
