3.2 X 350MM SUPERHARD 650 ELECTRODES X 5.0KG

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

HARDNESS: 58-60 HRC

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

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.
