Electrodes for welding high-alloy steels TsT-15

THE MAIN PURPOSE OF. Electrodes with basic coating for welding of critical components of structures made of austenitic steel grades Х20Н12ТЛ, Х12Н13Б, 12KH18N9T, 12Х18Н12Т and the like, operating at a temperature of 570-650°C and high pressure, and for welding of steel grades, when weld metal have requirements of resistance to intergranular corrosion. Welding in all spatial positions with direct current of reverse polarity. NTD GOST 9466-75, GOST 10052-75 (type e-08Х19Н10Г2Б) TECHNOLOGICAL FEATURES. The rod is made of wire marks SV-07Х19Н10Б according to GOST 2246-70. The diameter of the produced electrodes 3,0; 4,0 and 5,0 mm. CHARACTERISTICS OF MELTING OF THE ELECTRODES. Performance (for diameter 4.0 mm) 10.5 g/(A x h):1.3 kg/h. electrode Consumption per 1 kg of weld metal-1.7 kg. THE SPECIAL PROPERTIES. The weld metal is resistant to intercrystalline corrosion when tested according to the method of AMU GOST 6032-89. Characterized by high long-term strength. The content of ferrite phase in the deposited metal: the norm of 2.5-5.5 percent, typical of 3.7%.
