Welding electrodes HS-Fe8

EN 14700: E Z Fe8

it is recommended to hold the electrode vertically to the part
surfacing should be performed with a very short arc and the lowest possible current to prevent mixing with the base metal when surfacing on large surfaces in one layer
surfacing is carried out with transverse oscillations of the electrode with an amplitude of 2-3 times the diameter of the core, if it is
necessary to surfacing more than three layers, a buffer layer is applied
mechanical processing of surfacing metal - only by grinding

Special properties

ensure the production of deposited metal with high wear resistance under the conditions of abrasion with abrasive materials
the deposited metal is prone to the formation of small cracks, which, as a rule, do not reduce the operational stability of the deposited parts.
The hardness of the deposited metal is 58...62 HRC.
Full annealing - 780...820 °C ~ 25 HRC.
Forging after surfacing ~ 60...65 HRC.
1 layer on high-manganese steel ~ 30 HRC.
2nd layer on high-manganese steel ~ 45 HRC.
surfacing coefficient: 0,15…0,19 g/A•min
consumption of electrodes per 1 kg of deposited metal: 1,1…1,4 kg

HS-Fe8 electrodes are designed for surfacing solids layers on parts made of steel, cast steel and high-manganese steels, which are simultaneously subject to strong abrasive wear, shock and compressive loads. Typical areas of application are earthmoving, mining and stone processing industry: surfacing of teeth and cutting edges of excavators and bulldozers; screens, augers, hammers, jaw crushers of various mills, cutting edges on tools for cold processing and others details
