General characteristics

It is designed for automatic as well as semi-automatic open-arc or gas-shielded arc or submerged arc restoration and hard-facing of parts made of carbon and low-alloyed steels operating under conditions of metal-to-metal friction as well as alternating and impact loads.

Application

Typical applications are as follows: hard-facing of wheels and rollers of running gear for tracked vehicles, chambers and augers for rubber mixers, steel crankshafts, cordon shaft`s crosses, crane wheels, rollers of roller conveyors for transportation of hot metal, rollers of periodic rolling and couplers etc.

Weldability

The Formation of the weld bead	good
Separation of Slag	good
Deposition Rate, kg/h	4-13
Addiction Weld metal Cracking	moderate
Consumption per 1 kg of wire Weld metal, kg	1.05-1.2
Weld metal Hardness (HRC for 3rd-4th layer, unless otherwise stated)	after surfacing 40-50

Technological features

It is recommended for metal arc deposition at direct current of reverse polarity - DC ( +).
