OZL-25B high-alloy steel welding electrodes

THE MAIN PURPOSE OF. The electrodes are intended for welding of corrosion-resistant heat-resistant alloy grade KHN78T, cold-resistant and dissimilar steels. Welding in all spatial positions with direct current of reverse polarity. NTD GOST 9466-75, GOST 10052-75 (type e-10Х20Н70Г2МБ2В) THAT 14-4-935-78 TECHNOLOGICAL FEATURES. The rod of wire brand SV-KHN78T THAT 14-1-997-74. The diameter of the produced electrodes is 3.0 mm. CHARACTERISTICS OF MELTING OF THE ELECTRODES. Performance (for diameter 4.0 mm) 14.0 g/(A x h):1.0 kg/h. electrode Consumption per 1 kg of weld metal 1.4 kg. THE SPECIAL PROPERTIES. The combination of high mechanical and special properties of weld metal: heat resistant up to temperatures of 1000°C, long-term strength σ(850°C 100h) = 75Мпа, corrosion resistance Vкор not more than 0.02 mm/year (30% H2SO4+10% HNO3 at 800°C for 96ч). Perhaps the use of electrodes for welding of cast iron H2SO4HNO3. THE SYMBOL ELECTRODES E-10Х20Н70Г2М2Б2В-OZL-25B-3,0-Ø-VD GOST 9466-75, GOST 10052-75 E-087-B20 have THAT 14-4-935-78
