Hard surfacing of idlers and trucks links of bulldozers. For metal-to-metal wearing and light
Characteristics on usage
HF-500 deposits the weld metal of martensite structure, which has good toughness.
It is applicable to severe metal-to-metal wearing and abrasion accompanied by light impact.
It is difficult to apply machining on the weld metal.
Notes on usage
Preheat at 150°C and over in general.
In the case of multi-layer hard surfacing or hard surfacing onto large size casting steels and
forgings, low alloy steels, or high carbon steels, under layer welding with low hydrogen type
electrodes for mild steel should be applied.
