Hard Surfacing Arc Welding Electrodes

CH-45

CNS EH2B-B
JIS DF2B-B

DescriptionG

The deposited metal of CH-45 is designed to give an excellent hardness and resistance to cracking. It is suitable for hard surfacing of heavy duty intermetallic abrasion and light impact abrasion such as bulldozer parts. Its machining is a little bit difficult as welded condition.

ApplicationG

Hard surfacing of bulldozer links, idlers, rollers and sprockets, etc.

Instructions for welding :

  1. Preheat at 150J and over in general.

  2. In the case of multi-layer build-up welding or harden able steel welding, under lay with low hydrogen type electrode ( C-76 ).

  3. Dry the electrodes before use, at 300 ~ 350J for 30 ~ 60 minutes.
