|
|
| |
| 64 HRC in a Single Layer for Extreme Abrasion |
| OK Selectrode 84.84 has been developed with unique
alloying generating an equally unique microstructure
rich in carbides. This system assumes a high packing
density leaving virtually no matrix unsheltered. |
| |
| Dilution of carbide in base metal is minimum as expected
from the super convex bead shape. This. results in full
hardness attainment in one layer itself and uniform
hardness throughout the bead. |
| |
| ALLOY BASE |
| Fe, Si, C, Cr, Ti, V |
| |
| SPECIAL FEATURES |
- Full and uniform hardness in one layer only
- Distribution of light micro carbides for resistance to
abrasion by fine particles
|
| APPLICATIONS |
| Side ribs of oil drill bit and tri-cone rock roller bit. New
line concrete mixer paddles, dredger bucket tooth area.
Other typical applications include hammers, scrapers,
knives, shovel bucket and shovel teeth. |
| |
| PROPERTIES |
| Hardness : 62-64.5 HRC |
| |
| WELDING PROCEDURE |
- Use stringer beads. Weaving, if really unavoidable,
should be as less as possible
- If carpet coverage is required the overlap between
successive beads should be minimum
- Do not peen the bead while hot
- The hardness is not affected by cooling rate, however,
for best results employ normal air cooling
