Electrodes EA - 400 / 10U

WELDING ELECTRODES EA-400 / 10U (diameter 3; 4; 5 mm)

CLASSIFICATION: E-07H19N11M3G2F according to GOST 10052-75

LEGEND:E-07H19N11M3G2F -EA-400 / 10U-Ø-VD
                                      E-2214-B20

TECHNICAL REQUIREMENTS:GOST 9466-75, TU BY 100034500.029-2011

COATING:main

PURPOSE:

For the welding of corrosion-resistant austenitic steels 08Cr18Ni10Ti marks 12X18H10T, 10X17H13M2T and the like, when weld metal imposed resistance requirements for intergranular corrosion and operating in liquid corrosive non-oxidizing environments at temperatures up to 350 ° C and does not undergo heat treatment after welding, and and overlaying the second layer on the surface of the article from pearlitic.

In all spatial positions except the vertical "top-down", at a constant current of opposite polarity.

DIRECTIONS FOR USE:

Before welding, the surface to be welded must be cleaned to metallic luster.

In case of exceeding the permissible moisture content in the coating (0.3%) before use further electrodes are calcined at a temperature of 280-300 ° C for 40 minutes.
