Electrodes for Creep Resisting Steels

CROMOTHERME-5(MOD)

AWS: SFA 5.5 E8018-B6 EN ISO CODE: 3580-A E CrMo5 B 4 2 H5

Cromotherme-5 (MOD) is a basic coated, low hydrogen type electrode depositing a weld metal with 5Cr-0.5Mo ideally suited for welding of creep resisting steels of similar composition where superior notch toughness required at sub-zero temperatures. The weld metal possesses excellent creep properties up to 550 C. Typical applications include welding of 5Cr-0.5Mo steels in oil refinery, chemical plant, and equipments. Specifically applicable wherever prolonged heat treatments are involved.

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 (MOD) conforming to AWS: E8018 B6L is also available.
