- Tensile strength, MPa ≥ 510
- Yield strength, MPa ≥ 320
- Elongation, % ≥ 25
Welding electrodes Monolith M-20/25
Terms of use
- applied when welding in all spatial positions, except from top to bottom, with a constant current of reverse polarity
- welding must be performed with a short arc, without transverse oscillations, the edges should be cleaned before welding
Special properties
- very high reserve of austenity (EA-3)
- excellent mechanical properties of the deposited metal
- high welding and technological properties, easy separation of the slag crust, and the formation of a seam with a smooth transition to the base metal
- surfacing coefficient: 0.19...0.20 g/A•min
- consumption of electrodes per 1 kg of deposited metal: 1.4...1.5 kg
Monolith M-20/25 electrodes are designed for responsible welding structures made of alloyed steels of increased and high strength, heat-resistant and low-magnetic steels, steels of the type AK 23, AK 25, AK 27, as well as welding dissimilar steels.
