CLASSIFICATION: E-08H19N10G2B according to GOST 10052-75
LEGEND: E-08H19N10G2B-TST-15- Ø - WA
E-2453-B20
TECHNICAL REQUIREMENTS:GOST 9466-75, TU BY100034500.031-2011
COATING:main
PURPOSE:
For the welding of structures made of nodes austenitic steel grades H20N12TL, H16N13B, 12X18H9T, 12H18N12T and the like, working at a temperature of 570-650 ° C and high pressure, and also for welding steels of the same marks, when weld metal impose strict requirements of resistance to intergranular corrosion. In all spatial positions except the vertical "top - down", at a constant current of opposite polarity.
