CH-90
CH-90 is an electrode designed for abrasion resistance against heavy impact.The weld metal becomes austenitic by water cooling during welding, which has excellenttoughness and high work-hardening property.It is suitable for fill-up cavities of high manganese cast iron because of its high toughnessand crack resistance.

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