General characteristics

It is designed for open-arc or gas-shielded arc welding of Hadfield type high manganese steels (1.2C-l2Mn) or for arc welding of such steels with carbon and Mn alloyed steels.

Application

It is used for arc metal deposition of buffer layer prior hard-alloy cladding and repair welding under conditions of ore mining and processing plants and quarries.

Weldability

The Formation of the weld bead	good
Separation of Slag	good
Deposition Rate, kg/h	5-12
Addiction Weld metal Cracking	moderate
Consumption per 1 kg of wire Weld metal, kg	1.1-1.15
Weld metal Hardness (HRC for 3rd-4th layer, unless otherwise stated)	after surfacing HB 200-HB 260 after work hardening 40-47

Technological features

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