DIN EN 14700
E Z Fe1
The austenitic weld deposit of the high-alloyed stick electrode is corrosion resistant, work hardening, anti-magnetic and heat and thermal shock resistant up to 850°C. Depending on the high elongation (40%) the alloy is suitable for ductile buffer layers on old hardfacings and joining dissimilar and difficult to weld steels.
Joining of Mn – Steel and difficult to weld steels, buffer layers.
DIN EN 14700
E Fe9
Basic coated, AC-weldable electrode with approx. 140 % recovery. Due to the weld metal’s high tenacity and hardness, CORODUR 250 K is suitable for hardfacing on parts which are subject to extreme impact stress and cavitation. A considerable increase in wear resistance through strain hardening can be achieved by cold - hammering.
Excavator teeth, crushing hammers, rings in rotary furnaces, rail switch cores, rails, rollers, etc.
DIN EN 14700
E Fe6
AC-weldable electrode with approx. 120 % recovery for wear resistant surfacing on equipment parts and tools which are subjected to medium wear only. The dense and crack-free deposit is resistant to medium friction and compression, and highly resistant to shocks.
Due to its soft fusion and low spattering, the electrode can be used for welding in constrained positions. In spite of its basic coating it is well suitable for AC-welding. The weld metal can be machined with metal-cutting tools. Furthermore, surface layer hardening can be performed on machined areas. A buffer layer of CORODUR E 300 is recommended on base materials susceptible to work hardening.
Mainly used for heavy build up and as a cushion layer on crane wheels, shafts, slideways, wheel rims, conveyor screws, and bars.
DIN EN 14700
E Z Fe15
Tubular electrode filled with chromium carbide powder, suitable for hardfacing on parts which are mainly subject to abrasive wear, but also to impact stress. High amount of Cr- carbides in an austenitic matrix, very compact. Due to its special metallurgical composition, this electrode can be consumed with very low current. High hardness is achieved already in the first layer. Soft, quiet fusion. The weld metal is almost free of slag. A buffer layer of CORODUR 200 K is recommended prior to surfacing on old claddings.
Mainly used for hardfacing on pump bodies, mixer blades, agitator arms, concrete pumps, conveyer worms, and coke-oven slides, and agricultural machines, in civil engineering and in the cement industry.
