Flux cored wire of software - NP - 35V9H3SF
General characteristic
The flux cored wire of the software brand - NP - 35V9H3SF is intended for automatic building up under gumboil of the parts working in the conditions of thermal fatique and big specific pressure. It is recommended for building up on a direct current of the return polarity. The wire is issued diameter - 1,6 - 3,6mm.
Svarochno - technology properties
The recommended gumboil brand - AN - 20, AN - 26
Forming of the deposited bead - good
Separability of a slag crust - to 400 °C - good
Coefficient of building up, g/Ah - 10 - 16
Tendency of the built-up metal
to flawing - raised, it is necessary will precede. heating

Properties of the built-up metal
Excellent firmness against wear friction at the increased temperatures.
Thermal endurance - good. Resistance to blows - good. A workability cutting - satisfactory.
Technology features
Preliminary and concurrent heating of the built-up product up to the temperature of 350-400 °C is obligatory. After building up - slow cooling with a speed of 40 - 60 °C/h.
Application
Building up of steel rolls for hot rolling of pipes and a grade, knives of hot metal cutting, bikes of hammers, the pulling rollers of winders, brake drums.
