Low Heat Input Electrodes- Astraloy 445 |
Low Heat Input Electrodes:
high efficiency, high alloy, austenitic manganese steel, AC/DC electrode, for surfacing, build up and cushioning of austenitic manganese, medium carbon and low steels for wear due to severe impact and gouging abrasion by minerals .
|
Characteristics :
Stable and smooth arc produces weld deposits of good wash, shine and even finish.Ideal for multipass build up without cracking and spalling. Weld deposits are tough and work hardening and resistant to atmospheric corrosion.
|
 |
Applications :
Bucket teeth, mill hammers, crusher jaws, mantles, liners railway crossings in high traffic density and high speed traction etc.
