Hard Surfacing Arc Welding Electrodes

CH-60

CNS EH3B-B
JIS DF3B-B

Description¡G

CH-60 is a low hydrogen type electrode for surfacing worn parts of civil engineering, construction and mining machinery to be used without machining. Deposited metal of about 600 Vickers hardness and martens tic structure provides high toughness in spite of high hardness and excellent abrasion resistance to medium impact.

Application¡G

Surfacing of track rollers, crusher teeth, mill hammers and bucket lips.

Instructions for welding :

  1. Preheating at more than 150¢J is required.

  2. A buffer layer with low hydrogen electrode is required to surface hardening metal or to deposit multiple layers.

  3. Dry the electrodes before use, at 300 ~ 350¢J for 60 minutes.
