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.
