T400 is a material with high-temperature resistance, wear resistance, and corrosion resistance.
For the health and sustainable development of all mankind, the national Actively implement the National VI Standard (National Sixth Stage Motor Vehicle Pollutant Emission Standard), so higher requirements are put forward for the material of automobile exhaust valve. The T400 is widely used in GTR valves, turbochargers and wastegates and has unique advantages.

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.
