Welding wire Sv-08H20N9G7T
This wire is produced in accordance with GOST 2246−70, RD 03−613−03 and specifications 1220−005−84 823 540−2010. It is used for manual arc welding of critical parts of structures of steel austenitic grades: 12X18H9T, 08X18H10T, 08H18N12B and similar.
It is also used for sealing internal components that operate at high pressure and temperature of 570−650 °, and for welding of steels such as marks, if the welding seam is not imposed strict requirements of resistance to intergranular corrosion.
