Electrodes for welding high-alloy steels NZh-13

THE MAIN PURPOSE OF. Electrodes with basic coating for welding of important equipment made of corrosion-resistant hromonikelemolibdenovyh steel grades 10X17H13M2T, 10H17N13M3T, 08KH21N6M2T, and the like, operating at a temperature of 350°C, when the 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-09Х19Н10Г2М2Б) TECHNOLOGICAL FEATURES. The rod is made of wire marks SV-06Х19Н10М3Т SV-04Х19Н11М3 according to GOST 2246-70 AND TU 14-1-2370-78. The diameter of the produced electrodes 3,0; 4,0; 5,0 and 6,0 mm. CHARACTERISTICS OF MELTING OF THE ELECTRODES. Performance (for diameter 4.0 mm) of 13.0 g/(A x h):1.7 kg/h. electrode Consumption per 1 kg of weld metal 1.8 kg. THE SPECIAL PROPERTIES. The weld metal is resistant to intercrystalline corrosion when tested according to the method of AMU GOST 6032-89. The content of ferrite phase in the deposited metal of 2-10%.
