HARDFACING ARC 9 is a basic coated, AC/DC electrode for general purpose hard surfacing applications on carbon or austenitic manganese steels. This electrode deposits a tough, semi-austenitic C-Cr-Mn alloy capable of withstanding heavy gouging abrasion and impact.

• Tough Work-Hardening, Semi-Austenitic C-Cr-Mn Deposit
• Work Harden Under High Impact and Gouging Abrasion

Typical applications include rebuilding or overlay of crusher jaws, rolls, cones, hammers, tractor grousers, dozer blades, rippers, and conveyor chains. When welding on high carbon steels and alloy steels of high hardenability, preheat is recommended, or alternatively, a “buffer” layer of STABLEARC 18 or STABLEARC 16 may be used with a lower preheat temperature.

Deposit Properties:

HARDFACING ARC 9 deposits a tough, semi-austenitic, C-Cr-Mn hard surfacing alloy which is air hardenable and can be work-hardened to give a wear-resistant surface to withstand heavy impact and gouging abrasion.

Operational and Packaging Data:

• Electrode size: 3.2mm and 4.0mm.
• Electrode length: 350mm and 400mm.
• Electrode packaging: 5kg and 20kg.

*Recommended for DC+ or AC (minimum 55 OCV) operation.
