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 Fe14
Thickly coated high efficiency electrode with approx. 210 % recovery. The weld metal structure is ledeburitic, the alloy contains carbide forming elements of different kinds. CORODUR E 68 T is mainly used for applications where parts are subject to strong abrasive wear since the deposited alloy is highly resistant to abrasion, also when exposed to high temperatures. Smooth fusion, almost slag-free deposit. Prior to surfacing on old hardfacing layers a buffer layer with CORODUR 200 K is recommended
CORODUR E 68 T is mainly used for hardfacing on equipment in sintering plants, steel mills, coke oven plants, coal excavation and overburden removal, etc.
DIN EN 14700
E Fe16
Thickly coated, AC - weldable high efficiency electrode with approx. 170 % recovery. The weld metal deposited by CORODUR E 67 is of ledeburitic structure. The alloy is highly resistant to abrasion combined with impact stress. The special chemical composition of the alloy ensures good wear resistance in various temperature ranges. The fine-grained structure of the weld metal provides a solid matrix which retains the vanadium carbides also when subject to strong abrasion and ensures high crack-resistance. Smooth fusion, almost slag-free welding deposit. A buffer layer of CORODUR E 200 K is recommended prior to surfacing on old hardfacing.
Hardfacing on conveyor worms, clinker crushers, grates in mineral dressing equipment, concrete and cement pumps, etc.
DIN EN 14700
E Fe16
Thickly coated AC-weldable high efficiency electrode with approx. 240 % recovery for hardfacing of parts subjected to strong abrasion, friction at high temperatures. The weld metal structure is ledeburitic, the alloy contains carbide forming elements of different kinds. CORODUR E 65 provides extremely high resistance to abrasion also at temperatures up to 800°C. Smooth arc, very few slag. Prior to surfacing on old hardfacing layers a buffer layer with CORODUR E 200 K is recommended.
CORODUR E 65 is mainly used for hardfacing on conveyor worms, clinker crushers, blast furnace bells, grates in mineral dressing equipment, especially where live coal and slag are treated.
