:E-08Cr19Ni10Mn2B-ZТ-15-Ø-VD |
Purpose and scope
Welding electrodes ZT-15 are designed for welding of structural units made of chromium-nickel steels of the grades Cr20Ni12Тi-L, Cr16Ni13B, 12Cr18Ni9Тi, 12Cr18Ni12Тi and the like, operating at a temperature of 570-650 °C and high pressure, as well as for welding steels of the same grades when The weld metal is subject to stringent requirements for resistance to intergranular corrosion. Welding with ZT-15 electrodes in all spatial positions of the weld with direct current of reverse polarity.
