Chosun Welding Electrode CH-90 #6 (5.0MM)

Applications Hard-surfacing of crusher hammers, rail crossings and crusher jaws.
Characteristics CH-90 is an electrode designed for abrasion resistance against heavy impact.
The weld metal becomes austenitic by water cooling during welding, which has excellent
toughness and high work-hardening property.

It is suitable for fill-up cavities of high manganese cast iron because of its high toughness
and crack resistance.

Notes on usage (1) Water cool the weld metal during welding.

(2) Austenite type stainless steel electrodes should be used for under-laying on the base
metal other than 13%Mn steel.

(3) When the base metal of 13%Mn steel is hardened, cut-off the hardened zone before

(4) Dry the electrodes at 300~350℃ for 30~60 minutes before use.
