Electrodes for Creep Resisting Steels

MOLYTHERME (Extra)

AWS: SFA 5.5 E8018-D3 EN ISO CODE: 18275-B E 59 18-G P H5

Molytherme-Extra is a low hydrogen electrode yielding a weld deposit containing Mn- Mo. The electrode is ideally suited for welding steels of similar composition. The weld metal possesses good high temperature properties and has excellent toughness.

Precaution

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

2. Use short arc during welding.
