from
$66.75
TRW Engine Components is a recognized developer of valves and valve train components. A wide range of materials and material combinations are used to meet the engineering requirements in the different engine applications. Materials vary from ferritic martensitic steels (intake valves) and austentic CrMn based steels to extreme heat and corrosion resistant Nickel base super alloy for exhaust valves. To improve wear and corrosion resistance, valves can be chromium plated or nitrided. These coatings are used to improve the compatibility of the valve stem surface to the valve guide material. If necessary, exhaust valves (and in some cases also intake valves) can be hard-faced. In hard-facing, a more heat and wear resistant material is welded to form the valve seat. Seat hard-facing extends the valve life significantly.
