SA Nicro 625 SAW Arc Submerged




SA Nicro 625

 
CATEGORY 
TYPE 
Nickel - Chromium - Molybdenium alloy for SAW welding.
APPLICATIONS 
SA Nicro 625 is developed for welding and cladding nickel-based alloys such as alloy 625 or similar materials. This alloy can also be used for welding dissimilar nickel-based alloys to each other, to alloyed steels or to stainless steels and for joining 6% molybdenum super austenitic steels.. SA Nicro 625 is most commonly used in the chemical processing industry, pollution control equipment, marine equipment, nuclear reactor components, pump shafts. Also used in the aerospace industry for thrust reverser assemblies, fuel nozzles, after-burners and combustion systems.
PROPERTIES 

SA Nicro 625 is a solid drawn wire to be used for the submerged arc process in combination with FL 880 or FL 839 flux.
