Tribaloy 400 Material Cobalt Based Alloy Bearing bushing

TRIBALOY COBALT-BASED ALLOYS 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-400 combines excellent mechanical wear resistance with good corrosion

resistance. T-400 contains hard intermetallic phases of Mo and Si which impart excellent surface

properties over a wide temperature range. Often used in similar applications to Stellite12 or

Stellite 1. T-400 exhibits outstanding resistance to galling and corrosion.

CORROSION RESISTANCE

T-400 shows excellent corrosion resistance in Acetic Acid (concentration 50%, boiling) and in

Formic Acid (concentration 45%, boiling). Also in Phosphoric Acid (concentration 85%, 66°C)

excellent corrosion resistance has been observed.
