Electrodes for Creep Resisting Steels

CROMOTHERME-2L (MOD)

AWS: SFA 5.5 E8018-B3L

Low carbon, low hydrogen, iron powder electrode depositing 2.25Cr - l Mo weld metal having low level of impurities and exhibiting excellent toughness up to minus o 18 C. Weld metal retains its mechanical properties even after prolonged heat treatments. The weld metal displays excellent creep resistance with controlled hardness. Ideal for welding steels of similar composition to achieve tough weld metals.

Precaution

1. Re-dry the electrodes at 250-300 C for one hour, as per our standard recommended practice.

2. Use short arc and stringer bead.
