CORODUR® E 600

CLASSIFICATION

DIN EN 14700
E Fe3

GENERAL CHARACTERISTICS

CORODUR E 600 is an AC-weldable universal hardsurfacing electrode with 120 % recovery for rebuilding of machine parts subject to combined wear from abrasion and impact. Suitable for deposits on mild steel, steel castings and manganese steel. The pure weld deposit is only machinable by grinding. CORODUR E 600 has a soft but intensive welding character, a fine-structured seam
surface and excellent slag-removal properties. On high-carbon and crack-sensitive base materials, should be preheated to app. 200°– 300° C, depending on their composition and thickness. On highly crack-sensitive base materials and manganese steel, a buffer layer of CORODUR E 200 K or CORODUR E 250 K is recommended.

APPLICATION

Rollers, dredger chains, conveyors, hammers, dredger equipment, mining and earth-moving equipment.

CLASSIFICATION

DIN EN 14700
E Z Fe15

GENERAL CHARACTERISTICS

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.

APPLICATION

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.

CORODUR® E 300 K

CLASSIFICATION

DIN EN 14700
E Fe6

GENERAL CHARACTERISTICS

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.

APPLICATION

Mainly used for heavy build up and as a cushion layer on crane wheels, shafts, slideways, wheel rims, conveyor screws, and bars.

Datasheet

CORODUR® E 250 K

CLASSIFICATION

DIN EN 14700
E Fe9

GENERAL CHARACTERISTICS

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.

APPLICATION

Excavator teeth, crushing hammers, rings in rotary furnaces, rail switch cores, rails, rollers, etc.
