ASTRÄ HTB
 
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.
 
ALLOY BASE
Fe, Cr, Mo, Mn, Ni, C
 
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.
