Nicro 602 CA Tig (6025HT) GMAW-GTAW Solid wires




Nicro 602 CA Tig (6025HT)

 
TYPE 
Nickel based filler metal against extreme temperature conditions.
APPLICATIONS 
Welding similar alloys that have to resist extreme high temperature and for cladding steels or stainless steels to obtain a high temperature resistant surface against oxidation.
PROPERTIES 

Excellent welding properties with high build-up capacity and low dilution rate. Excellent resistance against temperature cycling conditions upto 1200oC and carburized medias. Excellent fatique strenght and creep properties.
