WELDING ELECTRODES OZL-9A (diameter 3; 4; 5 mm)

CLASSIFICATION: E-28H24N16G6 according to GOST 10052-75

LEGEND:E-28H24N16G6-OZL-9A - Ø - WA
                                     E-097-B20

TECHNICAL REQUIREMENTS:GOST 9466-75, TU BY 100034500.034-2011

COATING:main

PURPOSE:

For the welding of heat-resistant steels 12H25N16G7AR, 45H25N20S2, H18N35S2 and the like operating in oxidizing environments at temperatures up to 1050 ° C and in carburizing environments at temperatures up to 1000 ° C. They can be used for welding 20H23N13 steels 20H23N18. In all spatial positions except the vertical "top-down", at a constant current of opposite polarity.
