General characteristics

It is designed for automatic and semi-automatic open-arc or submerged arc metal deposition.

Application

Typical applications are as follows: cladding of rolls for continuous casting machines, sealing surfaces of general purpose fittings as well as fittings operated at temperatures up to 450 °C for gas and oil industries, plungers for hydraulic presses, ship`s shaft ends and others.

Weldability

The Formation of the weld bead	good
Separation of Slag	good
Deposition Rate, kg/h	4-14
Addiction Weld metal Cracking	moderate
Consumption per 1 kg of wire Weld metal, kg	1.05-1.05
Weld metal Hardness (HRC for 3rd-4th layer, unless otherwise stated)	after surfacing 35-46

Technological features

The deposited metal shows good resistance to wear and corrosion for metal-to-metal friction at room and elevated (up to 450 °C) temperatures and moderate resistance to burnouts and wear-and-tear.

Properties of the weld metal

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