NiCro 52M Tig

type 
Solid nickel base welding wire for Tungsten Inert Gas (Tig) welding.
applications 
Nicro 52M filler metal is used for welding nickel-chromium-iron (Inconel 690) alloys to themselves, and for dissimilar welding between nickel-chromium-iron alloys and steels or stainless steels. The applications include surfacing as well as clad-side welding. This product contains Boron and Zirconium to minize the tendency for ductility-dip cracking, while it is especially resistant to oxide "floaters" and inclusions.
Properties 

Excellent resistance against oxidizing media combined with high mechanical strength at room temperature but also at extreme high temperatures combined with high ductility due to the high chromium content. Alloy 690 was developped to offer greater resistance to stress corrosion in the nuclear industry, pure water invironment. Similar to FM 52 but the 52M is for nuclear application where a specific (very strict) chemical analysis is requested.
