* Stainless - Made as a one piece forged valve for higher strength and reliability.  Supertech uses mostly EV8 (21-4N) for Intake and Exhaust Valves, however there are other alloys that are used with different heat treatments to manufacture Valves for specific applications.

To address the issue of high heat, Supertech uses two different types of coatings:

Chrome Coating - Widely used in performance valves

Black Nitride - This is a hardening treatment that provides a smooth surface then chromed valves and produces less friction between stem and guide.


* Inconel 751 - Nickel Base Alloy - Nickel base alloy is used for exhaust valves that reach very high temperatures, such as those in turbo or supercharged applications.
