Description
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

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.
