Hardnell-350:

HARDNELL-350 is a rutile coated AC/DC(-) type electrode producing an air hardening type weld metal for hardfacing of carbon and low alloy steels. The weld metal is highly resistant to abrasive wear and has a fair degree of toughness.

Identification:Name Printed

Applications:Ideally suited for applications in which abrasion resistance is required with a fair degree of toughness. Typical applications include brake shoes, shear blades, wheels, cams, gears, pullies, drive sprokets, etc. Weld metal hardness: On mild steel two layers: 350-400 BHN

Welding current ranges and packing data for sizes manufactured:

Size(DxL) mm	5 x 450	4 x 450	3.15 x 450
Current(Amp)(DC+ or AC)	190-240	150-180	100-140
Qty.(kg.)/carton	40	70	100

Notes on usage:

Ensure the electrodes are dry, moist electrodes should be redried at 125°C for one hour.
Maintain short arc and avoid weaving.
Use suitable buffer layers and preheating depending on the material composition and thickness.
