Superhard 550

DESCRIPTION:

Hard surfacing electrode for tough - hard, impact tough And abrasive resistant surfacing on unalloyed and low alloyed materials with higher tensile strength.

HARDNESS : 57-60 HRC

FEATURES:                 

Hard surfacing electrode for tough - hard, impact tough And abrasive resistant surfacing on unalloyed and low alloyed materials with higher tensile strength.

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.
