Electrodes for Creep Resisting Steels

CROMOTHERME-2(MOD)

AWS: SFA 5.5 E9018-B3 IS: 1395 E63 B B3 2 6 Fe EN ISO CODE: 3580-A E CrMo2 B 4 2 H5

A low hydrogen iron powder electrode depositing 2.25Cr -1Mo weld metal having o low level of impurities and exhibiting excellent toughness up to -18 C. Weld metal retains its mechanical properties even after prolonged heat treatments. Ideal for welding steels of similar composition to achieve tough weld metals.

Precaution

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

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


NOTE: Low carbon version Cromotherme -2L (Mod) conforming to AWS : E8018 - B3L is also available.
