NII - 48G

WELDING ELECTRODES NII – 48G (diameter 3; 4; 5 mm)

CLASSIFICATION: E-10H20N9G6S according to GOST 10052-75

LEGEND:E-10H20N9G6S -NII-48g-d-BC
                              E-0050-B20

TECHNICAL REQUIREMENTS: GOST 9466-75. GOST 10052-75, TU BY 100034500.064-2016

COATING: main

PURPOSE:

Welding critical constructions of low-alloy steels and special steels, high-manganese 110G13L type steels and welding of these steels with chromium-nickel austenitic steel. In all spatial positions seam direct current reverse polarity.
