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.
• Average hardness equivalent to Rockwell C 64 - 68.
• High percentage of hardness retention up to 1600ºF (860ºC).
• Replaces Stellite in many applications.

TYPICAL MECHANICAL PROPERTIES :
Undiluted Weld Metal Maximum Value up to :
Hardness: 1st Pass RC 64-66 Vickers 840
2nd Pass RC 66-68 Vickers 880
Wear Co-efficient: 5%
APPLICATIONS :
For protecting all iron based parts subject to severe fine particle abrasion. Also excellent in wear applications at elevated temperatures.
MICROSTRUCTURE :
In the as welded condition the microstructure consists of an austenitic alloy matrix (bulk hardness of RC 61-63) and a large proportion of chromium and complex alloy carbides (RA 78-81).
RECOMMENDED CURRENT :
DC Reverse (+) or Straight (-), AC
WELDING POSITIONS :
Flat, Horizontal, Half up
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.
