Welding wire brand SV-07Х19Н10Б (SV-07Х19Н10Б-e) produce according to RD 03−613−03, GOST 2246−70 and technical conditi. 1220−005−84 823 540−2010. This wire is used for welding of products from corrosion-resistant chromium-Nickel steel grades 08KH18N12B, 08KH18N10T, 08KH18N12T and they are the same that operate in aggressive conditions, if the weld metal does not impose strict requirements for resistance to intergranular corrosion. This wire is also used for welding structures critical components of austenitic steels: 12Х18Н12Т, Х16Н13Б, Х20Н12Т-L, 12KH18N9T, and they are the same, operated at temperatures of 570−650°C, high pressure. Welding wire brand SV-07Х19Н10Б used for welding (welding) and the manufacture of electrodes of different types (OzL-7, TSN-12M, DH-15, CL-11).The percentage composition of (GOST 2246−70)

The wire components of the ferritic phase is regulated with the agreement of the parties.
In rolls of 85−100 kg, frame, metal coil К415, K300, plastic spools D200, 300. Produced wire diameter: 0.8 mm; 1.2; 1 mm; 1,6, 2 mm and 3 mm (allowable under the order production of the required size).
Temporary tear resistance of high-alloy, alloy wire corresponds fully to all norms.
