PP-NGM3F-50
Flux – cored for surfacing
The wire of PP-NGM3F-50 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 surfacing under fluxes AN-348; AN-348A; AN-60 is used in this case.
The wire is produced according to TU U 23165028-003:2009.
