Hard Facing Electrodes
Wear and Abrasion Resistance
Hard facing electrodes are used to deposit wear-resistant layers on metal surfaces subject to abrasion, impact, or metal-to-metal wear. They extend the working life of industrial components significantly.

| Weld Analysis (%) | Mechanical Properties | Application |
|---|---|---|
| C 2.00-4.00, Mn 0.50-2.50, Si 1.50-4.00, Cr 4.00-7.00, S 0.03 (max), P 0.03 (max) | As welded (Three layer deposit): 580-660 BHN; Current: AC/DC⁺ | For oil expeller worms, ploughshears, sand gravel, coal conveyor parts etc. |
| C 0.50-1.00, Mn 12.00-14.00, Ni 3.00 (max), S 0.03 (max), P 0.03 (max) | Hardness (As welded): 240-260 BHN; Hardness (Work hardened): 500-550 BHN; Current: AC/DC⁺ | Ideal for deposit on mild, carbon or low alloy steels and manganese steel. It is also used to resurface roll crusher, jaw crusher, shovel and excavator bucket tooth points, rail switch over points etc. |
| C 0.15-0.25, Mn 3.00-3.50, Si 0.50-0.80, Cr 0.30-0.70, S 0.03 (max), P 0.03 (max) | As welded (Three layer deposit): 350-450 BHN; Current: AC/DC⁺ | For pneumatic equipments, anvils, wheels flanges, sprockets, bucket chain links, bucket bases, guide rollers, actuating cams, bucket laddle tumblers. The electrode can be used on carbon, low alloy steels and on various grades of cast iron. |
| C 0.05-0.15, Mn 0.50-1.00, Si 0.30-0.50, Cr 2.00-4.00, S 0.03 (max), P 0.03 (max) | As welded (Three layer deposit): 350-450 BHN; Current: AC/DC⁺ | For shear blades, cold-punching dies, conveyor parts, crawler parts, axle, sprockets, latch bars, pulleys, brake shoes, large cog wheels and other steel castings, where resistance to abrasion combined with toughness is required. |
| C 0.40-0.60, Mn 0.60-1.20, Si 0.50-0.80, Cr 5.00-7.00, Mo 0.50-1.00, V 0.40-0.80, S 0.03 (max), P 0.03 (max) | As welded (Three layer deposit): 600-650 BHN; Current: AC/DC⁺ | It is very much suitable for hardfacing on carbon steels, low alloy steels and on cast irons. The applications include industrial knife edges, mill hammers, dredging bucket rims, shovel jaws and parts of agricultural and earth moving machinery. |
| C 0.50-0.80, Mn 0.30-0.60, Si 0.30-0.60, Cr 7.00-8.00, Mo 0.50-1.00, V 0.40-0.80, S 0.03 (max), P 0.03 (max) | As welded (Three layer deposit): 600-650 BHN; Current: AC/DC⁺ | The electrode is suitable for abrasion, impact or a combination of both, such as metal cutting and forming tools, hot and cold punching dies, drill bits, shears and croppers, oil expeller, crusher hammers, cane and bamboo cutting knives, crane wheels, conveyor buckets etc. |
