HARDFACING Mn-Ni is a smooth running, AC/DC electrode that deposits an austenitic steel weld metal for rebuilding and reinforcing matching manganese and manganese/nickel steels. Abrasion-resistant weld deposits such as HARDFACING ARC 33 can be applied directly onto HARDFACING Mn-Ni.

• Tough, Work hardenable Manganese Deposit
• For Rebuilding And Reinforcing 11-14% of Manganese Steels

Typical applications include the reclamation of crusher rods and jaws, bucket lips and teeth, grizzlies, liners, crossings, and other manganese steel components. These electrodes are not recommended for direct application onto mild or carbon steels – in this situation STAINARC 309L should be used as a “buffer layer”.

Deposit Properties:

HARDFACING Mn-Ni deposits a semi-stabilized, austenitic manganese steel weld metal that works hard under impact conditions. As the deposited weld is machinable & extremely tough, it offers excellent resistance to impact and high-stress gouging type abrasion.

Operational and Packaging Data:

• Electrode size: 3.2mm, 4.0mm and 5.0mm.
• Electrode length: 350mm and 400mm.
• Electrode packaging: 5kg and 20kg.

*Recommended for DC+ or AC (minimum 70 OCV) operation.
