|
| |
| Maximum Abrasion Resistance |
| OK Selectrode 84.78 gives an alloy rich deposit, which
offers best resistance to high-pressure abrasion by gritty
particles. |
| |
| The stainless bead is temper resistant upto 600°C. The
deposit resists corrosion and oxidation even at elevated
temperature. |
| |
| Relief cracks, transverse to the weld bead, are
desirable. |
| |
| ALLOY BASE |
| Fe, C, Cr |
| |
| SPECIAL FEATURES |
- Weld bead is convex and dilution is negligible
- Weld metal is having good corrosion resistance and
can withstand high temperatures
- Smooth arc
|
| APPLICATIONS |
| Highly recommended for earthmoving, construction,
cement and agriculture industries. |
