PP-NGM2S-30
Flux-cored wire for surfacing
The flux – cored wire of PP-NGM2S-25 grade is used for recovery of geometrical dimensions of wide nomenclature of parts such as shafts, axles, bushes, seats for bearings etc. The method of mechanized and semi-automatic surfacing is used in this case.
The wire is produced according to TU U 23165028-004:2009.
