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.
