WELDING ELECTRODES TSL-11 (diameter 3; 4; 5 mm)

CLASSIFICATION:E-08H20N9G2B according to GOST 10052-75

LEGEND:E-08H20N9G2B - TSL - 11 - Ø - WA
                                     E2005-B20

TECHNICAL REQUIREMENTS:GOST 9466-75, TU BY 100 034 500 016 -2006

COATING: main

PURPOSE:

Welding of critical structures of the corrosion-resistant CrNi steels 12X18H10T, 12X18H9T, 08H18N12T, 08H18N12B and the like, when weld metal strict requirements for resistance to intergranular corrosion. In all spatial positions except the vertical downward direct current reverse polarity.
