Description¡G
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.
Application¡G
Hard surfacing of
bulldozer links, idlers, rollers and sprockets, etc.
Instructions for welding :
-
Preheat at 150¢J and
over in general.
-
In the case of
multi-layer build-up welding or harden able steel
welding, under lay with low hydrogen type electrode
( C-76 ).
-
Dry the electrodes
before use, at 300 ~ 350¢J for 30 ~ 60 minutes.
