|
| |
| Resistance to Corrosion, Cavitation and Erosion |
Astra HTB is the only machinable alloy that resists
corrosion, cavitation alongwith erosion by suspended
particles on the strength of the unique recipe of this
electrode. The alloy also shows great resistance to
deform in service and hence maintains shape and
angularity of the original machined component at room
temperature and also upto 700°C. |
| |
|
|
Astra HTB endures in high temperature service as
well. It offers best combination of machinability, friction
and fatigue resistance, and shape retention at high
temperature. |

| SPECIAL FEATURES |
- Smooth running characteristics
- Oxidation resistance retained upto 1100°C
|
| APPLICATIONS |
| Joining and surfacing of hydel turbine blades, valve seats,
pump casings, gates, key-ways, machine components
exposed to corrosive atmosphere, matching parts
for which shape retention in service is of paramount
importance. |
