Hardfacing Electrodes
ES 260 / EN 14700: E Fe 4
Description
ES 260 is a basic coated electrode. It gives high oxidation resistant (up to 850°C) weld metals that also have a high wear resistance. It is resistant to wears of medium abrasions at high temperatures.

Applications
It is particularly used for repair applications of machine parts that are particularly exposed to wear by stone, coal, sand and soil. Loading machines, band plates, wear plates and parts of grinders can be hard faced with this electrode. It is recommended to use E S 260 in high temperature applications where oxidation resistance is more important than hardness and resistance to tempering like feed screws in furnaces. Hardening in oil or air at 920°C - 980°C, Softening in furnace at 680°C - 700°C.
