Electrodes of this group provide the getting of welding combinations, having corrosion resistance in the air, oxide, alkaline mediums and others aggressive mediums. Some grades of electrodes of this group have wider field of applications and they can be used not only getting the combinations with corrosion resistance, but as electrode, is providing high heat resistance and high temperature strength of metal clink.
