Welding wire brand SV-08Х20Н9Г7Т made in accordance with, RD 03−613−03, GOST 2246−70 and technical conditi. 1220−005−84 823 540−2010. This wire is used for manual arc welding of the most critical components of structures made of austenitic steel grades: 08KH18N12B, 12KH18N9T, 08KH18N10T, and similar. Wire is also used for parts of internal devices operated at t° 570−650°, high pressure, and used for welding steels of similar marks in the case when the seam is not present stringent requirements of resistance to intergranular corrosion.
Supply
In rolls of 85−100 kg, frame, metal coil К415, K300, plastic spools D200, 300. Produced wire diameter: 1 mm; 1.2; 1.6 mm; 2; 2.5 mm; 3, 4, 5 mm (allowable under the order production of the required size).
