Hardnell-OE:

HARDNELL-OE is a medium coated hardfacing electrode operating on AC/DC (+). Producing a very hard and sound weld metal which is highly resistance to abrasion and metal to metal wear. Welds are non-machinable type and can only be finished by Grinding. Exclusive electrode for hardfacing application specially designed for rebuilding of oil expeller worms.

HARDNELL-OE covers a wide area of applications needing appropriate hardness and prolonged service life, some of the pleasant features associated with HARDNELL-OE.
Soft and stable arc which is easy to strike and restrike.
Extremely low spatter.
Good slag detachability and weld bead of fine appearance.
Sound and porosity free weld metal.
Weld metal hardness: On mild steel two layers: 500-550 BHN

Notes on usage:

Ensure the electrodes are dry. In case of moisture Ensure, redry the electrodes at 200-250°C for one hour.
Use short & stringer beads.
Use suitable buffer layer and preheat depending on base material composition and thickness.
Avoid depositing more than two layers of HARDNELL. OE. In case heavy build-up is required, use buffer layer with ULTIMATE-16 or ULTIMATE-18 electrodes and then continue the built-up for two more
