Hardfacing Electrode

Superhard 650

Application

High alloyed air hardening type electrode depositing Non –MACHINEABLE weld metal, the deposit is free from Cracks, porosities and slag inclusions.

Hardness: 58-60

 

Welding Instruction

Guide electrode with a short arc. On materials sensitive to cracks use a buffer-layer of 18/8Mn type is recommended. Low alloyed, high carbon tool steels etc, have to be preheated to 200-400°C, depending on their composition and thickness. Slow cooling in still air after surfacing.
