DEPOSIT
HARDNESS - AS WELDED
550-600 Hv : 53-55 HRc on Mild steel 3rd layer. Hardness may
vary below or above the designed values depending on the types,
cooling and composition of the base metal . Deposit is Non -
machinable and normally can be shaped by grinding only. |
|
|
HEAT
TREATMENT
Amenable. On annealing at 6500C - 7000C for one Hour,
Hardness can be reduced to 350-400 HB
On the thermal quenching from 8500C - 9000C in oil/oil water Media,
designed hardness can regained.
|
|
|
| APPLICATIONS
For the hard surfacing of mild steel, Carbon steels, low alloy steels as an
extremely wear and abrasion resisting layer of average to serious toughness.
