Sv-08Х20Н9Г7Т welding wire is made according to RD 03−613−03, GOST 2246−70 and technical specifications. 1220−005−84 823 540−2010. The given wire is used for manual arc welding of the most critical units of constructions made of austenitic steel grades 08X18N12B, 12X18N9T, 08X18N10T as well as analogous ones. The wire is also used for parts of internal devices operating at t° 570−650 °, high pressure, as well as used for welding steels of similar grades in the case when the weld is not subject to stringent requirements of resistance to intergranular corrosion.
Delivery
In coils of 85−100 kg, K415, K300 metal wire spools, D200, 300 plastic wire spools. Wire diameters: 1mm, 1,2mm, 1,6mm, 2mm, 2,5mm, 3mm, 4mm, 5mm (sub-order production of the required size is possible).
