The electrodes ОЗЛ - 6
WELDING ELECTRODES OZL - 6 (diameter 3; 4; 5 mm)
CLASSIFICATION: E-10H25N13G2 according to GOST 10052-75
LEGEND: E - 10H25N13G2 - OZL-6 - Ø - WA
2005 E - B20
TECHNICAL REQUIREMENTS: GOST 9466-75, TU BY 100034500.014-2006
COATING: main
PURPOSE:
Intended for welding castings and forgings of high-alloy steels 20H23N13, 20H23N18 and the like, when the metal weld requirements impose resistance to intergranular corrosion. They can be used for welding of steels 20H25N20S2 grade and carbon steels with austenitic steels. In all spatial positions except the vertical "top-down", direct current reverse polarity.
