Supertech Inconel Exhaust Valve - Sodium Filled - Fiesta ST 1.6 Ecoboost
Running increased power on your Ford Fiesta ST 180? we can offer uprated exhaust valves.
We can offer uprated exhaust valves for your engine.
Made as a one piece forged valve for higher strength and reliability, Supertech use mostly EV8 (21-4N) for Intake and Exhaust valves but there are other alloys that we use along with different heat treatments to manufacture valves for different applications.
This is a hardening treatment that even though it is not widely used as the chrome coating, it has several benefits and is becoming very popular, mainly for European and Japanese applications.
The microhardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrided layer (microhardness is 800HV minimum). Surface finish is smoother than with chromed stems, having less friction between stem and guide.
Valve seat surface is harder with the nitrided layer, lasting longer with lead free fuels, alcohols, nitro or other "explosive" mixes. Matches any kind of seats (nodular iron seats, steel powder metal seats, hard aluminum-copper seats or beryllium copper seats).
