| High Temperature Chemical Inertness |
| OK Selectrode 93.66 deposits a highly crack resistant
weld metal of Stellite Gr. 6 type. The electrode is characterized
by its spatterless smooth arc and easy slag
detachability. The weld metal has excellent resistance
to friction, abrasion, impact, corrosion and oxidation and
abrasion at high temperature. These features make it
suitable for combined wear conditions. The alloy resists
spalling due to thermal cycling and has good sliding
properties. |

| SPECIAL FEATURES |
- Retains about 40 HRC hardness at 750°C
- Only solution to complex wear system
- Exceptional resistance to corrosion
|
| APPLICATIONS |
| Hardfacing of parts subject to wear at elevated temperatures
and also in corrosive environment like hot forging
tools, hot shear blades and dies, cutting edges, grab
tongs, hot punches, knives, chemical valve seats, steam
ends, pump sleeves, wear pads, screw conveyors, etc.
in chemical, petroleum and sugar industries and also in
steel plants. |

| WELDING PROCEDURE |
- Clean weld area for oil, grease and other impurities
- Preheat job wherever possible
- Hold electrode perpendicular to work piece and weld
in stringer beads
- Maintain interpass temperature 300°C or lower
- Cooling should be slow
