| Mac Hard E301 |
37-40 RC |
Hard Facing electrode for overlays on all ferrous metals. High impact loading and abrasion. Hardness 37 – 40 RC. |
| Mac Hard E304 |
57-59 RC |
High recovery hard facing electrode with a recovery rate of 110%. Hardness 57 – 59 RC. |
| Mac Hard E306 |
62-65 RC |
Hard facing electrode for overlays on all ferrous metals. Extremely severe abrasion. Foundry sand mills, impellor works. (Stands up to heat and corrosion). Hardness 62 – 65 RC. |
| Mac Hard E308 |
60-66 RC |
Hard facing electrode for applications on ferrous metals where rapid deposition and dot formation is required with little or no deslagging involved. For hard facing sugar cane crushing rolls welding in the vertical position whilst they are being slowly revolved. |
| Mac Hard E335T |
55-60 RC (Tubular) |
A highly alloyed tubular flux coated electrode for hard surfacing components subject to extreme abrasion. Alloy carbide content minimum 40%. Hardness 55 – 60 RC. |
| Mac Tungsten E375 |
75 RC (Tubular) |
Hard Facing Electrode for overlays on mild and alloyed steels, also cast iron. Deposits of tungsten carbide particles bonded in a tough steel matrix produces hardness of 75 RC. |
