Flux cored wire of software - NP-50X3CT
The self-protective flux cored wire of brand PP-Np-50X3CT is intended for automatic and semi-automatic building up by an open arch of the parts working in the conditions of friction of metal about metal and abrasive wear. It is recommended for building up on a direct current of the return polarity. The wire is issued with a diameter of 1,6 - 3,0mm.

Properties of the built-up metal
Wear resistance - good. Resistance to blows - satisfactory. A workability cutting - satisfactory.
At building up of massive products preheating to 250 - 300ºС is necessary.
Building up of carrying rollers of tractors and excavators, parts of conveyors, teeths of chain drums of multibucket excavators, rollers of roller conveyers, etc.
