T-800 alloys has better performance in galvanizing production line than stellite 4 and stellite 6, though stellite alloy also good enough for normal galvanizing production line. Whether you need stellite alloy or T-800 alloy, we can supply.
TRIBALOY COBALT-BASED ALLOYS
It is consist of a hard, intermetallic (Laves) phase dispersed
in a softer matrix of eutectic or solid solution. They exhibit outstanding resistance to wear and
galling, high corrosion resistance and are particularly suitable where lubrication is a problem. Wear
resistance of Tribaloy alloys is highly dependent on the volume percentage of Laves phase.
TRIBALOY T-800 was designed to resist high temperature wear and abrasion. It has exceptional
oxidation and corrosion resistance due to its high Cr content. T-800 is harder and has better
abrasive wear resistance than Tribaloy T-400.
NOTE:
Wear resistance of Tribaloy alloys is highly dependent on the volume percentage of Laves phase. Therefore, test results vary significantly with dilution and cooling rate and other thermal history.
Should be considered for valve trim, mechanical seals and thrust rings.
CORROSION RESISTANCE
T-800 shows excellent corrosion resistance in Acetic Acid (concentration 50%, boiling) and in Phosphoric Acid (concentration 85%, 66°C). Also in Sulphuric Acid (concentration 5%, 66°C) excellent corrosion resistance has been observed.
