Wire Sv-07H19N10B (St-07H19N10B-e)
This welding wire is manufactured in accordance with GOST 2246−70, RD 03−613−03 and specifications 1220−005−84 823 540−2010. It is used for welding articles made of nickel-chromium stainless steels 08X18H10T, 08H18N12B, 08H18N12T and similar such that operate in harsh environments in the case of absence of the metal seam stringent requirements for resistance to intergranular corrosion. Also, this wire is used for welding constructions of the critical parts of austenitic steel: H16N13B, H20N12T-L 12H18N12T, and similar 12X18H9T operated under high pressure and at a temperature of 570−650 ° C. Welding wire grade Sv-07H19N10B can be used for surfacing of parts and the production of various grades of electrodes (CG-15, CL-11, RLA-7, the TL-12M).
