Sv-07h19N10b (Sv-07h19N10b-e) welding wire is produced according to RD 03-613-03, GOST 2246-70 and technical specifications. 1220-005-84 823 540-2010. This wire is used for welding of corrosion-resistant chromium-nickel steel of 08X18H12B, 08X18H10T, 08X18H12T and analogous types, which operate in aggressive conditions if the metal weld is not subject to stringent requirements for resistance to intergranular corrosion. This wire is also used for welding critical structures made of austenitic steels 12X18N12T, X16N13B, X20N12T-L, 12X18N9T and similar types at working temperatures of 570-650°C under high pressure. Sv-07Cr19Ni10b welding wire is used for surfacing (welding), as well as for production of different types of electrodes (OZL-7, TsN-12M, TsT-15, TsL-11).

Welding process characteristics

Hardfacing of metal with welding wire is carried out in argon (inert gas). This improves the quality of formation of filling, root, facing layers of the weld and also stabilizes the burning of the arc.
