Classification:

AWS/SFA-5.5: E 7018-A1
IS-1395: E 49BA 126Fe

Characteristics:

An iron powder, hydrogen controlled, medium heavy coated electrode producing a 0.50% Mo weld deposit. The electrode has high welding efficiency, coupled with creep resistance properties at 525°C, and offers excellent mechanical properties.

Application:

• High-pressure boiler tubes and plates.
• Fabrication for welding 0.50% Mo and 1% Cr-0.5% Mo steels used for elevated temperature services up to 525°C.
• Suitable for fine-grained and creep-resistant steel welding.

Re-Dry Condition:

Re-dry the electrode at 250–300°C for one hour for best results.
