Electrodes for Creep Resisting Steels

MOLYTH ERME (EXTRA) MOD

AWS: SFA 5.5 E8018-D3

Molytherme(Extra)Mod 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. The weld metal meets SSCC and HIC test requirements.

Precaution

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

2. Use short arc and stringer bead.
