AWS – None
DIN 8555: E10-UM-65-GR
| FEATURES & APPLICATIONS |
For protecting all iron based parts subject to severe fine particle abrasion. Also excellent in wear applications at elevated temperatures.
- Smooth deposits enriched with Niobium Carbide and Chromium Carbide offer the ultimate combination of abrasion resistance and high temperature hardness retention.
- 1/3 the cost of Tungsten Carbide electrodes with superior wear properties.
- High percentage of hardness retention up to 1200°F (649°C).
- Replaces Stellite in many applications.
| All Weld Metal Analysis (Typical Weight %) |
Microstructure: In the as welded condition the microstructure consists of an austenitic alloy matrix and a large proportion of chromium and complex alloy carbides.
Flux Color: Black
| C | Mn | Si | Cr | Nb | Fe |
| 5 | .30 | 2 | 26 | 7 | Bal. |
| Typical Mechanical Properties |
Undiluted Weld Metal Maximum Value Up to:
Hardness: 1st Pass RC 59-60
2nd Pass RC 60-63
| Welding Current & Instructions |
Recommended Current: DC Reverse (+) or Straight (-), AC
| Diameter (mm) | 1/8 (3.25) | 5/32 (4.0) | 3/16 (5.0) |
| Minimum Amperage | 105 | 130 | 170 |
| Maximum Amperage | 135 | 170 | 240 |
Welding Techniques: Select the minimum required amperage and utilize a medium arc gap. For smooth flat welds use a 3 x weave. There is minimal slag which can be overwelded without prior removal. Only 2 passes are required for developement of the full benefits of this alloy. Cross crack stress relieving is normal.
Welding Positions: Flat, Horizontal, Half up
