Hardfacing Electrodes
ES 350 / EN 14700: E Fe 1
Description
ES 350 is a heavily coated basic electrode particularly used for wear conditions where impact stresses are considered and Mn-Cr alloyed frogs. It gives a weld metal that is resistant to deformations of high rolling forces including metal -to-metal friction. Weld metal is air hard enable and can be machined with carbide cutting tools. Hardness varies with respect to the number of passes and cooling rate. It has about % 115 metal recovery. Re-drying is 300°C min. 2 h.

Applications
It is used for hard facing of rollers, gears, rail crossings, switch points, brake shoes and crane wheels. Joining of heat treatable steels having a tensile strength of 80 - 90 kg / mm˛ is another application areas.
