DISSIMILAR METAL NO PRE HEAT!

SUPER CAST
The most outstanding universal “one product” type alloy for welding. 
Dissimilar combinations of steel, stainless steel, cast iron or
nickel based alloy with little or no preheat required
 
 
 
 
SPECIAL FEATURES:                                                   
 
§         Universal alloyed electrode for high heat and cryogenic applications.
§         Excellent high temperature strength and oxide resistance.
§         Good ductility for welding massive sections where postheat treatment is required.
§         Little or no preheat needed especially for massive or big dimension of work piece when pre-heating is not possible.
§         Extremely tough weld metal that work hardens.
§         High strength and high elongation weld metal properties.
 
 
 
APPLICATION:
 
§         Ideally suited for re-building of massive gear teeth especially for the sugar cane industry wherein because of the massive size dimensions of the gear when pre-heating can be ruled out.
§         For welding dissimilar combination of steel, stainless steel, cast iron and other nickel based alloy.

WELDING TECHNIQUES:
 
Clean area to be welded, removing all contaminating materials and old weld metal. Prepare joint edges. No preheat is usually necessary, nor desirable. Apply using any technique suited to the application – stringer bead, moderate or wide weaving, etc. Allow to cool and remove slag.
